Flipping between canvases

Hi All,
I have 10 histograms on a canvas divided as 2x5. I need to display 6 at one time and 4 at another without taking time to redraw them. I think that I should be drawing 6 on one canvas and 4 on a second canvas but I have not found the way to switch from one canvas to another. What is the simplest way?
Cheers,
Steve

Do

canvas1.cd(); canvas2.cd(); canvas1.cd(2); //cd to 2nd pad of canvas 2, etc
