XY Graph - How do I plot Multiple colors over one another depending on Case Structure
You can not (as far as i know) change color mid-plot, but you can simulate it by drawing segments. Eg. all positive numbers go into Plot 1 and all negative in Plot 2, set their colors before hand and you'll have a "multi colored plot" (as long as you don't show the Plot Legend) 😉
Another option would be to map the data points into a 2D array and use an intensity graph. Now you have full color control for each pixel and can chose from 256 colors. Now the memory use is constant forever!
Yet another possibility would be to use a 2D picture indicator. There is even a shipping example.
