The row_heights argument serves the same purpose for controlling the relative heights of rows in the subplot grid. For example, you can use subplots or axes to create multiple charts or graphs in one figure, hue, style, or size parameters to differentiate multiple variables in one chart or graph, overlay or stack options to combine multiple data sets in one chart or graph, and facet or grid functions to create multiple charts or graphs with different subsets of data. Aggregate touches in a chart alongside the pitch. This is because the Axes parameter passed is of default dimension (1,1) and hence not index-able.
