All Pie Chart labels outside of the Pie are drawn using the Font specified by this property. Since .NET Framework fonts are read-only objects, changing one or two style characteristics (e.g., boldness) of the Font object requires creating a reference to a new Font object with those style characteristics.
Developers that need to associate supplemental text within the Pie Chart, potentially with a different font selection, may do so through the addition of ChartTextAppearance to slices in the chart.
