I have some work getting ready for inclusion with 2D histograms, and they are colored by scalars. I was thinking about applying the same technique to scatter/line plots, but I am certainly interested in the approach you are using.</div><div><br></div><div>We have the color transfer function editor, and the approach I am using will tie in with that. I am not 100% clear on what you are doing, but would love to take a look. have a screenshot of my own on another system showing a 2D histogram colored by a scalar field. Do you want to push it to Gerrit at some point?</div><div><br></div><div>I have a backlog to get through, but would certainly like to get this functionality into the charts.</div><div><br></div><div>Marcus</div><br><div><div>On Nov 5, 2010, at 4:42 PM, Eric E.

I've never done any OpenGL programming, but I think I see how it can be done efficiently. Before I start playing around with it, though, I wanted to check whether this is something you guys are already implementing for near-term deployment?
