Re: Single plot overlaid on multiple base plots

Hi Li,

Once you overlay a plot onto another plot using "overlay", you cannot overlay it again on other plots.

If you need to overlay "A" multiple times, you can try making a copy of it:

plotB = plotA
plotC = plotA

overlay(plotBase1, plotA)
overlay(plotBase2,plotB)
overlay(plotBase3,plotC)

etc.
