Hi Dave,
It can be done. Take a look at my GraphClass.
It is a single Canvas with internal Graph Objects.

Hi Joe,
Thanks for the tip. Unfortunately, I don't know how else to achieve the
interface I have:

Each of the control elements (knobs, sliders etc.) is a canvas (actually a
custom subclass of a canvas). Each of the four wide rack devices is a
canvas, with the control elements on top of it. The entire window has a
background canvas, which is used to scroll the rack devices when the window
is smaller than the combined height of the four rack devices.
Using canvases as the control elements provides an excellent way for me to
deal with the controls as objects and subclasses.
How should I best achieve all of this without using the layered canvases?
Dave.
