I basically want to create a line with diamonds on the points (scatter shapes), but I want to skip points. I have data coming in at 200Hz. Drawing every point just makes a thick line. I would like to show a diamond on every 10th point as an example. Is there an easy way to do this? I realize I could just make one graph plot a solid line and then make another with only diamonds and only the points I want to see. Storing this data twice though is wasteful and I may not have the memory to do it.
