Hi,

I am developing a GUI using app designer. This contains multiple UIAxeses.

One of these UIAxeses is going to show site location in map using meshm and plotm functions. How can I convert an existing UIAxes to a map axes? or how can I import a map axes into the app designer?

unfortunately the axesm and worldmap functions open a new figure including a map axes which is not sutible for a standalone application. I have spent a large time for searching with no specific solution :(((

To import a map axes, it is only sufficient to change the parent of a map axes as follows:

% ... MapAxes is created in a new figure
% Change the Parent of the map axes
TempParent = MapAxes.Parent;
MapAxes.Parent = UIAxes.Parent;
% fit the size
MapAxes.Units = 'pixel';
MapAxes.Position = UIAxes.Position;
% delete the initial temperory UIAxes
delete(UIAxes);
% delete the temperory map figure
delete(TempParent);

Note some potential problems with this answer:

When you delete app.UIAxes at the end, that handle will be empty and you will not have access to the new axes handle unless you store is as a property of the app. I also recommend changing the units and position properties before changing the parent property. Another improvement would be to create the external figure with visibility off.

"...or how can I import a map axes into the app designer?"

You can copy the content of a map axis to a UI Axis. Here's a demo.

% Create map in external figure
korea = load('korea.mat');
Z = korea.map;
R = georasterref('RasterSize', size(Z), ...
  'Latlim', [30 45], 'Lonlim', [115 135]);
worldmap(Z, R)
meshm(Z, R)
ax = gca(); 
% Create UIAxes and copy content 
uif = uifigure(); 
uiax = uiaxes(uif); 
copyobj(ax.Children, uiax)
uiax.Visible ='off';

Would you be able to copy also a colorbar and the colormap?

Adam Danz 2023-10-2

Copy the colormap using

uiax.Colormap = ax.Colormap;

You may also want to copy the CLim property if you made any changes to the color limits.

As for the colorbar, recreate it in the new figure. If there are any important colorbar properties you set in the figure containing the map axes, you can copy the property values between the two colorbars.
