So I have data taken over 4 days where every 100 points, the test is re-run to see how the character of the line changes over time. The data in the beginning and end of each individual 100 point interval is pretty messy, so I want to find a way to plot the data (currently in a 131000x2 table in the Workspace) starting at points 20 and ending at 80. Essentially, out of every 100 data points, I only want to graph points 20-80. Can anyone help me figure this out? I imagine it would use some kind of "for" loop, but I'm pretty new at this so I don't really know for sure.
