Thread Subject: Updating the axes

If anyone's been around this past week or two they probably know I've
been working on making a GUI based panning program for use with
Matlab R13. I've got it all working, now I'm trying to make it look
nicer.

When I use WindowButtonMotionFcn, I update the axes whenever the
mouse moves. In my program, this causes for an ugly flashing as the
entire axes are redrawn every time the mouse moves a tiny bit.
Useable, but ugly as...well, you get the point.

Since I started this project I've found a few panning scripts which
I've been able to get some help from, but this I'm stuck on. All of
the panning scripts seem to be fine when panning, no ugly flashing,
and my GUI doesn't do anything more than the scripts for this
function, yet it's flashing constantly.

Is there a way to at least set a "refresh rate" or something like
that?

Try setting the figure property "doublebuffer" to 'on': this should
avoid flashing. (Double buffering works only when the figure
"Renderer" property is set to 'painters'.)

That did the trick.

I saw a reference to double buffer before, but didn't think about it
because it said it is set to 'on' by default! Apparently this is
wrong...or I'm just very confused.

In anycase, it works now, thanks!
