axesm
-Based Map Properties
Control axesm
-based map appearance and behavior
axesm
-based map properties control the appearance and
behavior of an axesm
-based map. By changing property values, you
can modify certain aspects of the axesm
-based map.
You can create an axesm
-based map (previously called map axes) by
using the axesm
, worldmap
, or usamap
function.
Properties That Control the Map Projection
AngleUnits
— Angular unit of measure
'degrees'
(default) | 'radians'
Angular unit of measure — Controls the units
of measure used for angles (including latitudes and longitudes) in the map.
All input data are assumed to be in the given units;
'degrees'
is the default. For more information on
angle units, see Angle Representations and Angular Units in the
Mapping Toolbox™ User's Guide.
Aspect
— Display aspect
'normal'
(default) | 'transverse'
Display aspect — Controls the orientation of
the base projection of the map. When the aspect is
'normal'
(the default), north in
the base projection is up. In a transverse
aspect, north
is to the right. A cylindrical projection of the whole world would look like
a landscape display under a 'normal'
aspect, and like a portrait under a
'transverse'
aspect. Note that this property is not
the same as projection aspect, which is controlled by the
Origin
property vector discussed later.
FalseEasting
— Coordinate shift for projection calculations
0
(default) | numeric scalar
Coordinate shift for projection calculations —
Modifies the position of the map within the axes. The projected coordinates
are shifted in the x-direction by the amount of
FalseEasting
. The FalseEasting
is
in the same units as the projected coordinates, that is, the units of the
first element of the Geoid
axesm
-based map property. False eastings and northings
are sometimes used to ensure nonnegative values of the projected
coordinates. For example, the Universal Transverse Mercator uses a false
easting of 500,000 meters.
FalseNorthing
— Coordinate shift for projection calculations
0
(default) | numeric scalar
Coordinate shift for projection calculations —
Modifies the position of the map within the axes. The projected coordinates
are shifted in the y-direction by the amount of
FalseNorthing
. The FalseNorthing
is in the same units as the projected coordinates, that is, the units of the
first element of the Geoid
axesm
-based map property. False eastings and northings
are sometimes used to ensure nonnegative values of the projected
coordinates. For example, the Universal Transverse Mercator uses a false
northing of 0 in the northern hemisphere and 10,000,000 meters in the
southern.
FixedOrient
— Projection-based orientation
[]
(default) | numeric scalar
This property is read-only.
Projection-based orientation — This read-only
property fixes the orientation of certain projections (such as the Cassini
and Wetch). When empty, which is true for most projections, the user can
alter the orientation of the projection using the third element of the
Origin
property. When fixed, the fixed orientation
is always used.
Geoid
— Reference spheroid definition
[1 0]
(default) | referenceSphere
object | referenceEllipsoid
object | oblateSpheroid
object | [semimajor_axis eccentricity]
Reference spheroid definition — The spheroid
(ellipsoid or sphere) for calculating the projections of any displayed map
objects. It can be an referenceSphere
, referenceEllipsoid
, or oblateSpheroid
object, or a
two-element vector of the form [semimajor_axis
eccentricity]
. The default value is an ellipsoid vector
representing the unit sphere: [1 0]
.
MapLatLimit
— Geographic latitude limits of the display area
[southern_limit northern_limit]
Geographic latitude limits of the display area
— Expressed as a two-element vector of the form
[southern_limit northern_limit]
. This property can be
set for many typical projections and geometries, but cannot be used with
oblique projections or with globe
, for example. When
applicable, the MapLatLimit
property may affect the
origin latitude if the Origin
property is not set
explicitly when calling axesm
. It may also determine the
value used for FLatLimit
.
MapLonLimit
— Geographic longitude limits of the display area
[western_limit eastern_limit]
Geographic longitude limits of the display area
— Expressed as a two-element vector of the form
[western_limit eastern_limit]
. This property can be
set for many typical projections and geometries, but cannot be used with
oblique projections or with globe
, for example. When
applicable, the MapLonLimit
property may affect the
origin longitude if the Origin
property is not set
explicitly when calling axesm
. It may also determine the
value used for FLonLimit
.
MapParallels
— Projection standard parallels
[lat]
| [lat1 lat2]
Projection standard parallels — Sets the
standard parallels of projection. It can be an empty, one-, or two-element
vector, depending upon the projection. The elements are in the same units as
the axesm
-based map AngleUnits
. Many
projections have specific, defining standard parallels. When an
axesm
-based map is based upon one of these
projections, the parallels are set to the appropriate defaults. For conic
projections, the default standard parallels are set to 15ºN and 75ºN, which
biases the projection toward the northern hemisphere.
For projections with one defined standard parallel, setting the parallels
to an empty vector forces recalculation of the parallel to the middle of the
map latitude limits. For projections requiring two standard parallels,
setting the parallels to an empty vector forces recalculation of the
parallels to one-sixth the distance from the latitude limits (e.g., if the
map latitude limits correspond to the northern hemisphere [0
90]
, the standard parallels for a conic projection are set to
[15 75]
). For azimuthal projections, the
MapParallels
property always contains an empty
vector and cannot be altered.
See the Mapping Toolbox User's Guide for more information on standard parallels.
MapProjection
— Map projection
character vector
Map projection — Sets the projection, and
hence all transformation calculations, for the
axesm
-based map. It is required in the creation of the
axesm
-based map. It must be a member of the
recognized projection set, which you can list by typing
getm('MapProjection')
or maps
. For
more information on projections, see the Mapping Toolbox User's Guide. Some projections set their own
defaults for other properties, such as parallels and trim limits.
Origin
— Origin and orientation for projection calculations
[latitude longitude orientation]
Origin and orientation for projection calculations
— Sets the map origin for all projection calculations. The latitude,
longitude, and orientation should be in the axesm
-based
map AngleUnits
. Latitude and longitude refer to the
coordinates of the map origin; orientation refers to an angle of skewness or
rotation about the axis running through the origin point and the center of
the earth. The default origin is 0º latitude and a longitude centered
between the map longitude limits. If a scalar is entered, it is assumed to
refer to the longitude; if a two-element vector is entered, the default
orientation is 0º, a normal projection. If an empty origin vector is
entered, the origin is centered on the map longitude limits. For more
information on the origin, see the Mapping Toolbox User's Guide.
Parallels
— Number of standard parallels
0
| 1
| 2
This property is read-only.
Number of standard parallels — This read-only property contains the number of standard parallels associated with the projection. See the Mapping Toolbox User's Guide for more information on standard parallels.
ScaleFactor
— Scale factor for projection calculations
1
(default) | scalar
Scale factor for projection calculations — Modifies the size of the map in projected coordinates. The geographic coordinates are transformed to Cartesian coordinates by the map projection equations and multiplied by the scale factor. Scale factors are sometimes used to minimize the scale distortion in a map projection. For example, the Universal Transverse Mercator uses a scale factor of 0.996 to shift the line of zero scale distortion to two lines on either side of the central meridian.
Zone
— Zone for certain projections
[]
or 31N
(default) | ZoneSpec
Zone for certain projections — Specifies the zone for certain projections. A zone is a region on the globe that has a special set of projection parameters. In the Universal Transverse Mercator Projection, the world is divided into quadrangles that are generally 6 degrees wide and 8 degrees tall. The number in the zone designation refers to the longitude range, while the letter refers to the latitude range. Most projections use the same parameters for the entire globe, and do not require a zone.
Properties That Control the Frame
Frame
— Frame visibility
'off'
(default) | 'on'
Frame visibility — Controls the visibility of
the display frame box. When the frame is 'off'
(the
default), the frame is not displayed. When the frame is
'on'
, an enclosing frame is visible. The frame is a
patch that is plotted as the lowest layer of displayed map objects.
Regardless of its display status, the frame always operates in terms of
trimming map data.
FFill
— Frame plotting precision
100
(default) | scalar plotting point density
Frame plotting precision — Sets the number of
points to be used in plotting the frame for display. The default value is
100
, which for a rectangular frame results in a plot
with 100
points for each side, or a total of
400
points. The number of points required for a
reasonable display varies with the projection. Cylindrical projections such
as the Miller require very few. Projections resulting in more complex
frames, such as the Werner, look better with higher densities. The default
value is generally sufficient.
FEdgeColor
— Color of displayed frame edge
'default'
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...
Color of displayed frame edge — Specifies the color used for the displayed frame. You can specify an RGB triplet, a hexadecimal color code, a color name, or a short name. By default, the frame edge is displayed in black.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]
, for example,[0.4 0.6 0.7]
.A hexadecimal color code is a string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Therefore, the color codes"#FF8800"
,"#ff8800"
,"#F80"
, and"#f80"
are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|---|---|
"red" | "r" | [1 0 0] | "#FF0000" | |

FFaceColor
— Color of displayed frame face
'none'
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...
Color of displayed frame face — Specifies the
color used for the displayed frame face. You can specify an RGB triplet, a
hexadecimal color code, a color name, or a short name. The default,
'none'
, means no face color is filled in.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]

FLatLimit
— Latitude limits of map frame relative to projection origin
[southern_limit northern_limit]
Latitude limits of map frame relative to projection
origin — The map frame encloses the area in which data
and graticule lines are plotted and beyond which they are trimmed. For
non-oblique and non-azimuthal projections, which have quadrangular frames,
this property controls the north-south extent of the frame. If a projection
is made oblique by the inclusion of a non-zero rotation angle (the third
element of the Origin
vector),
FLatLimit
still applies, but in the rotated
latitude-longitude system rather than in the geographic system. In the case
of azimuthal projections, which have circular frames,
FLatLimit
takes the special form [-Inf
radius]
where radius is the spherical distance (in degrees or
radians, depending on the AngleUnits
property of the
projection) from the projection origin to the edge of the frame.
Note
In most common situations, including non-oblique cylindrical and
conic projections and polar azimuthal projections, there is no need
to set FLatLimit
; use
MapLatLimit
instead.
FLineWidth
— Frame edge line width
2
(default) | scalar
Frame edge line width — Sets the line width of the displayed frame edge. The value is a scalar representing points, which is 2 by default.
FLonLimit
— Longitude limits of map frame relative to projection origin
[western_limit eastern_limit]
Longitude limits of map frame relative to projection
origin — The map frame encloses the area in which data
and graticule lines are plotted and beyond which they are trimmed. For
non-oblique and non-azimuthal projections, which have quadrangular frames,
this property controls the east-west extent of the frame. If a projection is
made oblique by the inclusion of a non-zero rotation angle (the third
element of the Origin
vector),
FLonLimit
still applies, but in the rotated
latitude-longitude system rather than in the geographic system. The
FLonLimit
property is ignored for azimuthal
projections.
Note
In most common situations, including non-oblique cylindrical and
conic projections, there is no need to set
FLonLimit
; use MapLonLimit
instead.
TrimLat
— Bounds on FLatLimit
[southern_limit northern_limit]
This property is read-only.
Bounds on FLatLimit
— This
read-only property sets bounds on the values that axesm
and setm
will accept for the
MapLatLimit
and FLatLimit
properties, which is necessary because some map projections cannot display
the entire globe without extending to infinity. For example,
TrimLat
is [-90 90]
degrees for
most cylindrical projections and [-86 86]
degrees for the
Mercator projection because the north-south scale becomes infinite as one
approaches either pole.
TrimLon
— Bounds on FLonLimit
[western_limit eastern_limit]
This property is read-only.
Bounds on FLonLimit
— This
read-only property sets bounds on the values that axesm
and setm
will accept for the
MapLonLimit
and FLonLimit
properties, which is necessary because some map projections cannot display
the entire globe without extending to infinity. For example,
TrimLon
is [-135 135]
degrees for
most conic projections.
Properties That Control the Grid
Grid
— Grid visibility
'off'
(default) | 'on'
Grid visibility — Controls the visibility of
the display grid. When the grid is 'off'
(the default),
the grid is not displayed. When the grid is 'on'
,
meridians and parallels are visible. The grid is plotted as a set of line
objects.
GAltitude
— Grid z-axis setting
Inf
(default) | scalar
Grid z-axis setting — Sets the z-axis location for the grid when displayed. Its default value is infinity, which is displayed above all other map objects. However, you can set this to some other value for stacking objects above the grid, if desired.
GColor
— Color of the displayed grid
'default'
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...
Color of the displayed grid — Specifies the color used for the displayed grid. You can specify an RGB triplet, a hexadecimal color code, a color name, or a short name. By default, the map grid is displayed in black.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]
, for example,[0.4 0.6 0.7]
.A hexadecimal color code is a string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Therefore, the color codes"#FF8800"
,"#ff8800"
,"#F80"
, and"#f80"
are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

GLineStyle
— Grid line style
:

used when the grid is displayed. You can specify any line style supported by
the MATLAB
line
function. The default line style is a dotted line
(that is, ':'
).
GLineWidth
— Grid line width
0.5
(default) | scalar
Grid line width — Sets the line width of the
displayed grid. The value is a scalar representing points, which is
0.5
by default.
MLineException
— Exceptions to grid meridian limits
[]
(default) | vector
Exceptions to grid meridian limits — Allows specific meridians of the displayed grid to extend beyond the grid meridian limits to the poles. The value must be a vector of longitudes in the appropriate angle units. For longitudes so specified, grid lines extend from pole to pole regardless of the existence of any grid meridian limits. This vector is empty by default.
MLineFill
— Grid meridian plotting precision
100
(default) | scalar plotting point density
Grid meridian plotting precision — Sets the number of points to be used in plotting the grid meridians. The default value is 100 points. The number of points required for a reasonable display varies with the projection. Cylindrical projections such as the Miller require very few. Projections resulting in more complex shapes, such as the Werner, look better with higher densities. The default value is generally sufficient.
MLineLimit
— Grid meridian limits
[]
(default) | [north south]
| [south north]
Grid meridian limits — Establishes latitudes beyond which displayed grid meridians do not extend. By default, this property is empty, so the meridians extend to the poles. There are two exceptions to the meridian limits. No meridian extends beyond the map latitude limits, and exceptions to the meridian limits for selected meridians are allowed (see above).
MLineLocation
— Grid meridian interval or specific locations
30
(default) | scalar | vector
Grid meridian interval or specific locations —
Establishes the interval between displayed grid meridians. When a scalar
interval is entered in the axesm
-based map
MLineLocation
, meridians are displayed, starting at
0º longitude and repeating every interval in both directions, which by
default is 30º. Alternatively, you can enter a vector of longitudes, in
which case a meridian is displayed for each element of the vector.
PLineException
— Exceptions to grid parallel limits
[]
(default) | vector
Exceptions to grid parallel limits — Allows specific parallels of the displayed grid to extend beyond the grid parallel limits to the International Date Line. The value must be a vector of latitudes in the appropriate angle units. For latitudes so specified, grid lines extend from the western to the eastern map limit, regardless of the existence of any grid parallel limits. This vector is empty by default.
PLineFill
— Grid parallel plotting precision
100
(default) | scalar plotting point density
Grid parallel plotting precision — Sets the
number of points to be used in plotting the grid parallels. The default
value is 100
. The number of points required for a
reasonable display varies with the projection. Cylindrical projections such
as the Miller require very few. Projections resulting in more complex
shapes, such as the Bonne, look better with higher densities. The default
value is generally sufficient.
PLineLimit
— Grid parallel limits
[]
(default) | [east west]
| [west east]
Grid parallel limits — Establishes longitudes beyond which displayed grid parallels do not extend. By default, this property is empty, so the parallels extend to the date line. There are two exceptions to the parallel limits. No parallel extends beyond the map longitude limits, and exceptions to the parallel limits for selected parallels are allowed (see above).
PLineLocation
— Grid parallel interval or specific locations
15
(default) | scalar | vector
Grid parallel interval or specific locations —
Establishes the interval between displayed grid parallels. When a scalar
interval is entered in the axesm
-based map
PLineLocation
, parallels are displayed, starting at
0º latitude and repeating every interval in both directions, which by
default is 15º. Alternatively, you can enter a vector of latitudes, in which
case a parallel is displayed for each element of the vector.

property. The default point size is
9.
FontUnits
— Units used to interpret the FontSize
property
'points'
(default) | 'normalized'
| 'inches'
| 'centimeters'
| 'pixels'
Units used to interpret the FontSize
property — When set to normalized
,
the toolbox interprets the value of FontSize
as a
fraction of the height of the axes. For example, a normalized
FontSize
of 0.1
sets the text
characters to a font whose height is one-tenth of the axes' height. The
default units ('points'
) are equal to
1/72
of an inch.
FontWeight
— Select bold or normal font
'normal'
(default) | 'bold'
Select bold or normal font — The character weight for all displayed grid labels.
LabelFormat
— Labeling format for grid
'compass'
(default) | 'signed'
| 'none'
Labeling format for grid — Specifies the
format of the grid labels. If 'compass'
is employed (the
default), meridian labels are suffixed with an “E” for east
and a “W” for west, and parallel labels are suffixed with an
“N” for north and an “S” for south. If
'signed'
is used, meridian labels are prefixed with a
“+” for east and a “-” for west, and parallel
labels are suffixed with a “+” for north and a
“-” for south. If 'none'
is selected,
straight latitude and longitude numerical values are employed, so western
meridian labels and southern parallel labels will have a “-”,
but no symbol precedes eastern and northern (positive) labels.
LabelRotation
— Label Rotation
'off'
(default) | 'on'
Label rotation — Determines whether the meridian and parallel labels are displayed without rotation (the default) or rotated to align to the graticule. This option is not available for the Globe display.
LabelUnits
— Specify units and formatting for grid labels
'degrees'
(default) | 'dm'
| 'dms'
| 'radians'
Specify units and formatting for grid labels —
The display of meridian and parallel labels is controlled by the
axesm
-based map LabelUnits
property, as described in the following table.
LabelUnits
value | Label format |
---|---|
'degrees'
| decimal degrees |
'dm' | degrees/decimal minutes |
'dms' | degrees/minutes/decimal seconds |
'radians' | decimal radians |
LabelUnits
does not have a default of
its own; instead it defaults to the value of AngleUnits
at the time the axesm
-based map is constructed, which
itself defaults to degrees. Although you can specify 'dm'
and 'dms'
for LabelUnits
, these
values are not accepted when setting AngleUnits
.
MeridianLabel
— Toggle display of meridian labels
'off'
(default) | 'on'
Toggle display of meridian labels — Specifies whether the meridian labels are visible or not.
MLabelLocation
— Specify meridians for labeling
scalar | vector
Specify meridians for labeling — Meridian
labels need not coincide with the displayed meridian lines. Labels are
displayed at intervals if a scalar in the axesm
-based
map MLabelLocation
is entered, starting at the prime
meridian and repeating at every interval in both directions. If a vector of
longitudes is entered, labels are displayed at those meridians. The default
locations coincide with the displayed meridian lines, as specified in the
MLineLocation
property.
MLabelParallel
— Specify parallel for meridian label placement
'north'
(default) | 'south'
| 'equator'
| scalar
Specify parallel for meridian label placement
— Specifies the latitude location of the displayed meridian labels.
If a scalar latitude is specified, all meridian labels are displayed at that
latitude. If 'north'
is specified, the maximum of the
MapLatLimit
is used; if 'south'
is
specified, the minimum of the MapLatLimit
is used. If
'equator'
is specified, a latitude of 0º is
used.
MLabelRound
— Specify significant digits for meridian labels
0
(default) | integer scalar
Specify significant digits for meridian labels
— Specifies to which power of ten the displayed labels are rounded.
For example, if MLabelRound
is -1, labels are displayed
down to the tenths. The default value of
MLabelRound
is 0; that is, displayed labels have no
decimal places, being rounded to the ones column
(100).
ParallelLabel
— Toggle display of parallel labels
'off'
(default) | 'on'
Toggle display of parallel labels — Specifies whether the parallel labels are visible or not.
PLabelLocation
— Specify parallels for labeling
scalar | vector
Specify parallels for labeling — Parallel
labels need not coincide with the displayed parallel lines. Labels are
displayed at intervals if a scalar in the axesm
-based
map PLabelLocation
is entered, starting at the equator
and repeating at every interval in both directions. If a vector of latitudes
is entered, labels are displayed at those parallels. The default locations
coincide with the displayed parallel lines, as specified in the
PLineLocation
property.
PLabelMeridian
— Specify meridian for parallel label placement
'west'
(default) | 'east'
| 'prime'
| scalar
Specify meridian for parallel label placement
— Specifies the longitude location of the displayed parallel labels.
If a longitude is specified, all parallel labels are displayed at that
longitude. If 'east'
is specified, the maximum of the
MapLonLimit
is used; if 'west'
is
specified, the minimum of the MapLonLimit
is used. If
'prime'
is specified, a longitude of 0º is
used.
PLabelRound
— Specify significant digits for parallel labels
0
(default) | integer scalar
Specify significant digits for parallel labels
— Specifies to which power of ten the displayed labels are rounded.
For example, if PLabelRound
is -1, labels are displayed
down to the tenths. The default value of PLabelRound
is
0; that is, displayed labels have no decimal places, being rounded to the
ones column (100).
