MATLAB: Is there any alternative for ‘patch’ command in uiaxes

app designerpatchuiaxesuifigure

We have recently been encouraged at my work to start using the new ui controls in matlab (e.g. uifigure, uiaxes). However, I have just found that uiaxes does not support the 'patch' command. Is there any way round this? Will this be supported soon? Being able to draw transparent shapes on my plots is fundamental to the kind of thing I'm trying to show.

Hey! It seems that with version 2017b, patch command is supported in App designer. Cheers! https://www.mathworks.com/help/matlab/creating_guis/graphics-support-in-app-designer.html

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
