_______________________________________________________
Details:
Steps to reproduce:
1. load the attached .mat file bugXXXX.mat
2. plot the data using:
patch ("vertices", [X Y], "faces", faces, "facecolor", [0.5 0.7 0.9],
"edgecolor", [0.6 0.6 0.6])
3. click Zoom in" button
4. Zoom out using scroll wheel until plotted data disappear completely (axes
still visible).
5. Then zoom back in
==> Result:
No problems.
But,
6. Repeat step 2
7. Type "axis equal" in command window
8. Repeat steps 3 - 5
Result:
==> After a few zoom-out steps (9 in my case) the plot and axes suddenly
disappear completely. Zooming back in they don't reappear.
In addition, after step 2 (w/o "axis equal"), zooming out (with zoom out
button active) by clicking in the plot, the plot zooms out but after a few
clicks in the plot often zooms back in to full extent.
In other tries, zooming in behaves similarly, the plot zooms out unexpectedly
in some cases.
