08 Mar 2011 displaytable Legible display of N-dimensional data tables with color highlighting of entries. Author: Matt Caywood

Hi Ralf, "negative zero" was actually a fundamental issue with Matlab's printf (on some platforms)

I agree it is an annoyance, and have submitted a new version that should fix it.
01 Feb 2011 SCATTERCLOUD Scatterplot over a density cloud. Author: Steve Simon

To fix the glaring centering bug, change these lines from:

xEdges = [xEdges(2) - xDiff,xEdges(2:end-1), xEdges(end-1) + xDiff];
yEdges = [yEdges(2) - yDiff,yEdges(2:end-1), yEdges(end-1) + yDiff];

TO:

xEdges = [xEdges(2) - xDiff,xEdges(2:end-1), xEdges(end-1) + xDiff] + xDiff/2;
yEdges = [yEdges(2) - yDiff,yEdges(2:end-1), yEdges(end-1) + yDiff] + yDiff/2;

In the future, if there's a "simple" fix, why not post it and be helpful?

Good idea, Jan. I've added an example. Hope you find the code useful.

Hi Rebecca, check the documentation for waitfor -- 'ButtonDownFcn' doesn't change, so I don't think you can waitfor it.

You might change TogglePlot so that it would change some property of the figure, something like setappdata(get(src,'Parent'),'Done') then waitfor(fig,'AppData');

I haven't tested this but I expect something like it would work.

Bass, this is designed to replace the built-in figure zoom/pan tools, which I found slow and inadequate.

I believe the reason it doesn't work with them is that we overlay the original plot with an invisible patch that reliably traps mouse clicks. So you're zooming & panning the invisible patch, not the plot.

If instead you attach the togglesubplot event handler to the original plot, you can use it with the zoom/pan controls -- but then the grow/shrink control won't be very reliable.

I like this function very much. However, it appears that 0 is displayed sometimes as -0. Can this been fixed?

It would be helpful to show the example in the description here. Then I do not have to download before I can understand, what the function does.
