Gets or sets the group type for the axes which are used to plot the series data.
An AxisGroup enumeration member specifying the axis group.
Use the AxisGroup to create secondary axes on the chart. When the AxisGroup is set to the AxisGroup.Secondary value, a group of secondary axes is created. Use the ChartObject.SecondaryAxes property to access these axes.
You cannot make all series on the chart secondary. An exception occurs when changing the AxisGroup value for the series which is the only primary series of a chart.
If you try to change the AxisGroup for a series whose type does not allow secondary axes, an exception occurs.
The example below demonstrates how to display a secondary axis on a chart. The secondary axis group is used to plot data of a specific series, for which the Series.AxisGroup property is set to AxisGroup.Secondary value.
