# uiaeroaltimeter

Create altimeter component

Since R2018b

## Syntax

``altimeter = uiaeroaltimeter``
``altimeter = uiaeroaltimeter(parent)``
``altimeter = uiaeroaltimeter( ___ ,Name,Value)``

## Description

example

````altimeter = uiaeroaltimeter` creates an altimeter in a new figure. MATLAB® calls the `uifigure` function to create the figure.The altimeter displays the altitude above sea level in feet, also known as the pressure altitude. It displays the altitude value with needles on a gauge and a numeric indicator. The gauge has 10 major ticks. Within each major tick are five minor ticks. This gauge has three needles. Using the needles, the altimeter can display accurately only altitudes between 0 and 100,000 feet.For the longest needle, an increment of a small tick represents 2000 feet and a major tick represents 10,000 feet.For the second longest needle, a minor tick represents 20 feet and a major tick represents 100 feet. For the shortest needle a minor tick represents 200 feet and a major tick represents 1,000 feet. For the numeric display, the gauge shows values as numeric characters between 0 and 9,999 feet. When the numeric display value reaches 10,000 feet, the gauge displays the value as the remaining values below 10,000 feet. For example, 12,345 feet displays as 2,345 feet. When a value is less than 0 (below sea level), the gauge displays `0`. The needles show the appropriate value except for when the value is below sea level or over 100000 feet. Below sea level, the needles are set to `0`, over 100,000, the needles stay set at 100,000. NoteUse this function only with figures created using the `uifigure` function. Apps created using GUIDE or the `figure` function do not support flight instrument components. ```

example

````altimeter = uiaeroaltimeter(parent)` specifies the object in which to create the altimeter.```
````altimeter = uiaeroaltimeter( ___ ,Name,Value)` specifies altimeter properties using one or more `Name,Value` pair arguments. Use this option with any of the input argument combinations in the previous syntaxes.```

## Examples

collapse all

Create an altimeter component named `altimeter`. By default, the function creates a `uifigure` object for the indicator object.

`altimeter = uiaeroaltimeter`
```altimeter = Altimeter (0) with properties: Altitude: 0 Position: [100 100 120 120] Show all properties``` Create a figure window to contain the altimeter component, then create a altimeter component named `altimeter`.

```f = uifigure; altimeter = uiaeroaltimeter(f)```
```altimeter = Altimeter (0) with properties: Altitude: 0 Position: [100 100 120 120] Show all properties```

## Input Arguments

collapse all

Parent container, specified as a `Figure` object created using the `uifigure` function or one of its child containers: `Tab`, `Panel`, `ButtonGroup`, or `GridLayout`. If you do not specify a parent container, MATLAB calls the `uifigure` function to create a new `Figure` object that serves as the parent container.

### Name-Value Arguments

Specify optional pairs of arguments as `Name1=Value1,...,NameN=ValueN`, where `Name` is the argument name and `Value` is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose `Name` in quotes.

## Output Arguments

Altimeter component, returned as an object.
