We use matplotlib v3.1.3 for our plot generation. The top level global applies global configuration. It currently supports a limited subset of the rcParams: font_size, font_family, agg_path_chunksize. A future version will support all rcParams keys. The global["plot_options"] can be used to configure plot options for all plots and series. This is convenient if you want to apply an option to all plots/series without having to define it for each one. We support all matplotlib Line2D properties.

plot_options can also be defined at the plots level, which will apply to each series within a plot, or at the series level, which will apply to the specific series. All plot_options are merged together when plotting each series, with the series plot_options having the highest precedence.
