Does this answer your question? Or can you describe what you want the display to do?

I guess what I'm looking for doesn't exist yet (I'd like arbitrary X - not necessarily monotonically increasing).

One of my simulation tools simulated the path that the robot would drive in autonomous mode. I wanted to plot that path on an X-Y plane to be sure that it was going where I wanted it to. The robot could have X and Y coordinates that increase or decrease over the duration of the path (i.e. not monotonically increasing). The solution I came up with was to store the X-Y path data in large vectors during the simulation, then create a graph after the simulation was finished. That resulted in a bit of frustration (and a lot of "why won't this let me do that??"). I finally figured out how to do what I wanted, but it took me a while to get there.
