Create mapping values to analyze data in groups. Map each of the data values to a mapping value. You can then use the mapping value in the analysis to plot data density across groups of values. For example, a test case requires data in a few regions. You therefore want to analyze the distribution of data across regions. The data contains a States column. You can create mapping values such as East, West, North, South, and assign states to a mapping value. You can then analyze the data distribution across regions.
You can map data values to a single mapping value. You can map multiple data values to the same mapping value.
