Plotting gps coordinates in Appdesigner

Hello everyone,

I have to plot a map in gps coordinates inside a UIAxes in Appdesigner, but using "geoplot" function the app plots the map in an other image outside the App. I tried give "app.UIAxes3" (which is the graph where I want to plot gps coordinates) as first argument of the function, but Matlab gives error saying that I have to use latitudinal/longitudinal coordinates.

Here is the code, and an image showing the map outside the app, instead i want the map in the UIAxes marked in red

%Function to plot TrackMap
 
              function results = geoplotter(app)
              
              app.track=geoplot([app.lat],[app.lon])
             
              end
              

Maybe is there another way to write geoplot function in appdesigner or a different functions to read and plot map in gps coordinates?

Many Thanks

Hi,

Starting in R2018b, you can create additional plots in App Designer. Most of these plots require a different type of parent object and additional lines of code in your app. All of them use normalized position units by default.

For your case,

Create the geographic axes by calling the geoaxes function. Specify the parent container as the first input argument (for example, app.UIFigure). Then, call the plotting function with the axes as the first input argument. For example:

latSeattle = 47 + 37/60;
lonSeattle = -(122 + 20/60);
gx = geoaxes(app.UIFigure);
geoplot(gx,latSeattle,lonSeattle)

This might help you!

Hi, thanks for responding.

I tried but Matlab gives me this error:

Hi,

You cannot make an axes a child of axes itself, you can append geoaxes to a UIFigure only.

Ok, I see.

So there's a way to plot gps coordinates in a UIAxes graph? Maybe using other functions instead geoplot?

[Harsha Priya Daggubati]

You can use Panel instead,

latSeattle = 47 + 37/60;
lonSeattle = -(122 + 20/60);
gx = geoaxes(app.Panel);
geoplot(gx,latSeattle,lonSeattle)

it doesn't work on uiaxes please help me

You can use a panel or tab instead of UIAxes. This link should be helpful.
