Ideally you would save the inner position of the axis, do the plotting, and then restore the inner axis position. But the 'InnerPosition' property of axes in app designer is read-only (why!?? who knows). So here's a work around.
In your plotting function,
- Before plotting, save the original read-only 'InnerPosition' values
- Do your plotting
- Calculate the difference between the new inner position and old inner position
- Change the 'Position' value so that the inner position matches what it used to be.
axInnerPos = app.UIAxes.InnerPosition; %1) store original inner position of axis
% plot() %2) do your plotting, etc.
innerPosDiff = axInnerPos - app.UIAxes.InnerPosition; %3) calculate difference between original and current inner ax pos.
app.UIAxes.Position = app.UIAxes.Position + innerPosDiff; %4) change the 'position' so inner position matches original values
