'Declaration Public ReadOnly Property ChartText As ChartTextCollection
public ChartTextCollection ChartText {get;}
Chart Text and Pie Labels each have their own uses, and differ in two key respects. Whereas the PieLabelAppearance class governs text labels appearing on the outside of the pie slices of a Pie Chart (optionally connected to slices by "leader lines"), the ChartText collection accepts ChartTextAppearance objects that each represent the style and content of an individual label appearing on one of the pie slices. Another difference is that Chart Text applies to most 2-D chart types, where as PieLabelAppearance only applies to Pie Charts.
Pie Charts normally render one row of data, so the Row of the chart text will typically be initialized to 0. The Column should be set to the column index of the pie slice (not necessarily the same as the slice number of the pie wedge). Developers must also set the Visible property to True for any chart text labels displayed.
