Hi Greg, The classes TH1, TH2 and TH3 have constructors with fix and variable bin sizes. You can build the arrays binsX and binsY with any algorithm like you describe. Note that we currently have a restriction in the visualisation of variable bin size 2-d histograms. Options lego, surf cannot be used.
