[ROOT] zooming more than one TGraph

Hi,

I have a TRootEmbeddedCanvas divided in a certain number of pads. Each pad
has a TGraph object. Each TGraph plots data from different channels but
all the channels have the same x and y axis range. By selecting a region
with the mouse in one of the TGraphs, I would like to be able to zoom
every other TGraph object on the same region as the one clicked
by the mouse.

If anyone has an idea of how I could manage the mouse to implement such
a feature, or if someone already overode some zooming methods, you might
be able to give me a hint.

thanks
