Plot hierarchy

NOTE: This currently WIP

ArviZ has hierarchical plot-function structure.

Level 1: Atomic axis (1 axis)

The first level functions operates against one axis with one or more variables. These functions include:

• plot_one_kde
• plot_one_hist
• plot_one_trace
• plot_one_box
• plot_one_rug

The common input and default values for these functions are

*arr: one or two {ndarray, str}
source: {xarray.Dataset, pandas.DataFrame,bokeh.ColumnDataSource}; optional
ax: {matplotlib.axis, bokeh.figure}; optional
labels: one or two {str, bokeh.Text}
line_kwargs: {dict}; optional
    line properties
fill_kwargs: {dict}; optional
    area properties
special_kwargs: {dict}; optional
    special plot specific properties
backend: {"matplotlib","bokeh"} 

Atomic plot returns the axis.

Level 2: Combined atomic plots
