MATLAB: Does Alt-Click fail to zoom on a figure in MATLAB 7.0 (R14) on Linux or Mac machines

alt+clickMATLABoutzooming

I use the following code to plot a figure and enable zooming:

plot(1:10);
zoom on

Clicking on the resulting figure zooms in on it. On Windows machines, if I then Alt-Click on the figure, the figure is zoomed out. However, this is not true on Linux and Mac machines.

On Linux machines, Alt-Click causes no effect. On Mac machines, Alt-Click brings up a context menu.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB 7.0 (R14) in the way that Alt-Click is handled differently on different platforms when zooming is enabled.

There are no workarounds.

MATLAB: Does the cursor disappear on the figure when I use the GINPUT function on Mac OS in MATLAB 7.0.1 (R14SP1)

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB 7.0.1 (R14SP1) on Macintosh platforms in the way the GINPUT function handles drawing the cursor on the figure.

As a workaround, adding a legend to the figure brings back the cursor (even if you later hide it). Therefore, modifying the code as follows resolves the issue:

pcolor (64*rand(100));
legend('location','westoutside')
legend('hide')
ginput

MATLAB: Data Cursor Problem wtih Alt-Click

Mel, I can reproduce the error by doing the following:

Start GUIDE
Add a menu item, label it "File" and give it the tag "FileMenu"
Save the GUI to "Seg_gui.fig"
Edit the Seg_gui.m file and remove the function "FileMenu_Callback"
Run the GUI and press Alt.

This now causes the error, and it is due to the graphical menu object having a callback set, but that callback not existing in the Seg_gui.m file.

To fix the error you can either manually add a function of that name back into the Seg_gui.m file (just copy one of the other callback function lines and change the name), or you can edit the GUI in GUIDE again to completely remove the callback on that menu:

Open Seg_gui in GUIDE.
Go to Tools->Menu Editor.
Select the File menu.
In the Callback text box, delete all the text. This will remove the callback.
Press OK on the Menu Editor.
Save the gui.
