11.36 Line Chart Skewed Distributions

The plot informs us about the skewed nature of the amount of rainfall recorded for any one day, but we lose a lot of resolution at the low end.

Note that we use a subset of the dataset to include only those observations of rainfall (i.e., where the rainfall is non-zero). Otherwise a warning will note many rows contain non-finite values in calculating the density statistic.
