union or overlap of two plots
type: item
description: Hello, I have two plots of data on the same axes. I need to figure out the area of their overlap. I think defining the data as two polygons and using polyfillv() would help, but I'm not sure about how to do this. I was also considering finding all of the interceptions between the two plots, and using tsum() to calculate the area of each subsection of overlap. Anyways, if there's an easier way, I'd appreciate it. -kedmond
