A few (Summed)Plot improvements, envelope example
Leftover from https://gitlab.cern.ch/cp3-cms/bamboo/-/merge_requests/98 : make it easier to subclass Plot
(and only do RResultPtr
dereference in SummedPlot
if necessary).
Calculating a variation from other variations (e.g. qcdScale{i}
to up and down by taking the minimum and maximum) can then be done by overriding Plot.produceResults
(added to the nanozmumu example for illustration - thanks @kjaffel and @swertz for the original implementation).
