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));
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
CurrentAxes = append('app.UIAxes',num2str(i));
exportgraphics(fig, [CurrentAxes '.jpg']);
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
