I'm trying to transition over to app designer but am having trouble with uiaxes objects. When I use imagesc with a uiaxes object, the automatic limits are badly choses, leaving data off screen in one direction and whitespace on the others. Standard (axes) behavior has the limits automatically set properly and won't let the user drag beyond where there is data.
How to I acheive this in uiaxes. Is there a workaround?
Minimum broken example:
C = magic(3);
ax = uiaxes();
im = imagesc(ax,C);
You can drag beyond the limits!

I understand from your question that you either want to autoscale the axes limits (or) want to disable the interactivity of the UIAxes.
For autoscaling:
C = magic(3);
ax = app.UIAxes;
axis (ax,'tight')
im = imagesc(ax,C);
For disabling interactivity of the UIAxes component:
disableDefaultInteractivity(ax)
You can also hide the toolbar so that the user cannot zoom in/out:
ax.Toolbar.Visible = 'off';
