Plotting a line in a worldmap

Dear all. I am trying plot a satellite track in the form of a line over lake Michigan. I loaded world map and then tried plotting the track (vectors X_47 and Y_47) but it didnt show up as a line. This may be because its coordinate is different. Pls help me

worldmap([41 47], [-89 -84]) lakes=shaperead('worldlakes','UseGeoCoords',true); X_47=(41.709091:0.5:43.127372);Y_47=(-87.476139:0.5:-86.340273); griddata(42.419908, -86.91495,1); load coastlines plotm(coastlat,coastlon); plotm(coastlat,coastlon);

hold on; plot(X_47,Y_47,'r');

With PLOTM, you need to define the map axes first like:

load coastlines 
axesm sinusoid;
plotm(coastlat,coastlon);

but GEOSHOW is much easier to use than PLOTM:

worldmap([41 47], [-89 -84]) 
lakes=shaperead('worldlakes','UseGeoCoords',true); 
X_47=(41.709091:0.5:43.127372);
Y_47=(-87.476139:0.5:-86.340273); 
% griddata(42.419908, -86.91495,1); 

load coastlines 
geoshow(coastlat,coastlon); 

hold on; 
h = geoshow(X_47',Y_47');
h.Marker = 'o'; h.Color = 'r';
