Split Percentile Plot

You can use split percentile plots to compare distributions of some attribute across various groups. There is one percentile plot for each group.  (To split a percentile plot, drop an attribute on the axis not occupied by the numeric attribute.)

Here, we're plotting income (in thousands) against sex. We see the income distribution for males and females in a sample of 133 people in Berkeley, California.

An percentile plot shows the distribution of continuous (numeric) data. There is one point for each case. It is plotted at its attribute value and its percentile value.
