Interactive plot

Hi everyone I was wondering, lets say we have a gui that at some point will generate a plot. Is there a way to somehow add the ability to manipulate that plot, for example use the muse to grab and move it, and at the same time keep track of the its changes in a variable?

There are several related submissions in the FEX:

• http://www.mathworks.com/matlabcentral/fileexchange/23304-moveit2-move-a-graphical-object-with-the-mouse

I assume, they conatin enough code, which can be re-used for your purpose.

Grabbing a plot and moving it (within a fixed axes drawing area) is implemented by changing the XLim and YLim properties of the axes (see also the xlim() and ylim() commands).

You can get the current XLim and YLim properties before you update the plot, and then after the data update you can apply the limits again.
