Here is an example I pulled from a program I wrote a while back. Basically, I use an enum (and yes I should be using a ring instead of the enum) to select what data I want out of a 2D array. If you select none, that plot is blank on the chart. I usually have four plots per chart so the chart does not look to cluttered up and I have had as many as 150 parameters in each enum to select from. Hope this is what you are looking for.
