Prettier histograms

[mspraggs]

Can this be done? By "prettier" I mean for example filled stacked histograms like in this paper: http://arxiv.org/pdf/1602.01767.pdf. I'm not so familiar with Gnuplot, so I don't know it's limitations.

Gnuplot does not have a stacked mode for this particular style I use here (I found the real histogram style cumbersome). However, it is very easy to stack the data manually from the C++ side. You could have a class similar to PlotHistogram called PlotStackedHistogram with a const std::vector<Histogram> & as an argument.
Please feel free to give it a shot, I can help you with the gnuplot syntax if you need. The actual code of PlotHistogram should give a good starting point.

Okay thanks. If I find the time I'll give it a try.
