Moveit2 - Move a graphical object with the mouse.

This is really a small hack that I wanted to share just to inspire more people to make interactive Matlab graphics. Use it as is or use the code as a template to do more advanced stuff.

Here is how it works (for a 2-D patch):

% First make the patch ...
t = 0:2*pi/20:2*pi;
X = 3 + sin(t); Y = 2 + cos(t); Z = X*0;
h = patch(X,Y,Z,'g')
axis([-10 10 -10 10]);
% Then make it movable
moveit2(h);

It also works for e.g. pcolor and plot:

% Adjust data to fit hypothesis using the mouse ... :-)
a = plot(rand(10,10));
moveit2(a);
