Scruffy::Layers::Average

Author:Brasten Sager
Date:August 7th, 2006

An ‘average’ graph. This graph iterates through all the layers and averages all the data at each point, then draws a thick, translucent, shadowy line graph indicating the average values.

This only looks decent in SVG mode. ImageMagick doesn‘t retain the transparency for some reason, creating a massive black line. Any help resolving this would be useful.
