The Dumbledraw module receives, processes and plots ROOT histograms (TH1F) according to the common style in the Higgs to tau tau analyses.

A basic introduction is given here. A detailed example showing most of the functionalities is given in example_script.py.

Every plot is created as an instance of the class plot containing one or more instances of the class subplot:

plot = dumbledraw.Plot([[0.5, 0.48]], <style args>)

This creates two subplots with a gap between 48% and 50% of the plotting area. The subplots are defined via a list of split points (top down), which can be doublets in case of gaps.

Histograms can be registered in a (sub)plot under a given nickname and modified e.g. normalized to other histograms before plotting:

plot.subplot(0).add_hist(histogram1, "signal")
plot.subplot(0).add_hist(histogram2, "background")
plot.subplot(0).normalize("signal", "background")

Many methods of subplot are also implemented for plot calling the same method for all subplots, e.g.:

plot.add_hist(histogram1, "signal")

Apply individual graph styles optionally making use of the Dumbledraw.styles module and finally plot and save selected histograms:

plot.subplot(0).setGraphStyle("signal", "hist", linecolor=styles.color_dict["ggH"], linewidth=3)
plot.subplot(0).Draw(["signal"])
plot.save("plot.pdf")

The rootfile_parser module is an independent module that can be used to easily extract the histograms from the CombineHarvester ROOT files.
