Using a loop to export UIAxes

Hi all,

I am using app designer and am trying to use a loop to export 5 figures. Below is the code I am using.

            for i = 1:5
                CurrentAxes = append('app.UIAxes',num2str(i));
                exportgraphics(CurrentAxes,append('TestName',num2str(i),'.jpg'))
            end

I get the error "Error using exportgraphics. First parameter must specify the axes or chart object."

I suspect that CurrentAxes shouldn't be in string formatt, but I'm not sure what to change it to. Would anyone have an idea?

CurrentAxes in your code is a string. The first argument to exportgraphics should be a figure or axes handle.

Try this code

fig = uifigure;
a = axes(fig);
for i = 1:5
    bar(a,magic(randi(5)));
    CurrentAxes = append('app.UIAxes',num2str(i));
    exportgraphics(fig, [CurrentAxes '.jpg']);
end

Repalce 'fig' in code above, with your app.UIAxes handle and you should get the desired result.

Also, you can use the [ ] to append multiple strings, don't need to use the append() function
