@Kitonum Thank you for such a quick response. So is this approach what you used in your CountoursWithLabels program to make produce the gaps in your contours where the contour label texts appear (but using multiple clipping regions somehow)? I'm really new to Maple programming, coming from a mathcad background. Basically my question here was just trying to isolate the a way to put my own labels on a contour plot by having a "white background" for the text so that it created a break in the contour instead of plopping right on top of the line. My approach for locating the labels would have been a tinker toy compared to what you did, just having them all along one axis where the essentially, but anyway that is what I was trying to do. But it looks like you cannot generically “cover up” sections of a plot with a shape- good to know.
But having explained this, I see that someone responded to my question on your thread about your ControursWithLabels, and it looks like I just didn’t know how to pass my procedure as an unevaluated expression. Hopefully I will learn these things well. I’ve used Mathcad for >25 years and its frustrating coming from a high degree of knowledge about a tool to asking newbie questions 😊.
