This seems to be a problem with the way DeltaGraph places the graph on the clipboard. Canvas seems to think its a picture object, not a PICT. The problem is a little different if you try to paste it into MacDraw II. It will say that pasting a PICT2 may cause a loss of some color data. It does, however, paste the graph without an opaque background, i.e. other objects will show through. So, I guess you could use MacDraw II, or paste them first into MD and then copy them into Canvas. Since I vastly prefer Canvas, that's what I'd do.
