Specifically, it will show you how to use facet_grid to create small multiple charts. Themes can be used to give plots a consistent customized look. Once you have Series 3 ("total"), then you can use the overlay feature of matplotlib and Seaborn in order to create your stacked bar chart. Note that, the argument legend. This vignette covers the function plot_grid(), which can be used to create table-like layouts of plots. add_legend() plt. 3 The grammar of graphics. label_wrap_gen() uses base::strwrap() for line wrapping.

The reason the legend and dodging doesn't work the original way you're doing it is that setting hue in FacetGrid and setting it in pointplot are different. kdeplot, "PetalLengthCm") \. The reason is that for most of the plots, the hue variable also determines position on the categorical axis, which FacetGrid can't do anything about, and so the right usage is to delegate hue conditioning to the function call. I then generated the yearly averages as geom_points using a facet_grid, which generated a 24x24 grid. pyplot as plt from matplotlib. Reverse legend order. factorplot (). We will use R's airquality dataset in the datasets package. Although the highest weekly sales exceeded 25K dollars, over 90% of the data had weekly sales less than 5K dollars.
