Scatter graphs – PB Docs 2022

Scatter graphs show xy data points. Typically you use scatter
graphs to show the relationship between two sets of numeric
values.Non-numeric values, such as string and DateTime datatypes, do
not display correctly.

Scatter graphs do not use categories. Instead, numeric values
are plotted along both axes—as opposed to other graphs, which have
values along one axis and categories along the other axis.

For example, the following data shows the effect of speed on
the mileage of a sedan:

Here is the data in a scatter graph:

You can have multiple series of data in a scatter graph. You
might want to plot mileage versus speed for several makes of cars in
the same graph.
