Chart Plots

A plot controls the visual representation of data in a chart.

This section describes properties that are supported by all chart plots.

The Plot Border

A border is drawn around the outside of most plot types. It's possible to change the appearance of the border by modifying the paint and stroke used to draw it.

An outline is drawn around all four sides of the data area. Note that each of the plot's axes may also draw a line along the edge of the data area. See the Axis Line Visible attribute of the axis.
