Write text onto an ActiveX component.

I'm using the VTChart ActiveX component that comes with BCB3. I align it to
the client window of an MDI application's child window. I need to write text
on top of this display, and I need to sense the color of pixels as well.
Both are easily done if a component has a Canvas property, but this ActiveX
component doesn't. Is there a way to accomplish these things without a
Canvas property?
