Mon, 01 Jan 0001 00:00:00 +0000

This article explains how to add custom colors to pie chart slices/sectors. By default, pie charts use the Microsoft Excel default template. To use other colors, redefine the colors in the chart.

To set a custom color for a pie chart’s individual slices or sectors:

Access the Series object’s ChartPoint.
Assign the color of your choice using the ChartPoint.GetForegroundColor() property.

This article also explains how to:

Set a chart’s category data.
Set a chart title linked to a cell.
Adjust the chart title font settings.
Position the legend.

ChartPoint.GetForegroundColor() is not specific to pie charts but it can be used for all types of charts.
