What is the use of the commonSeriesOptions in Chart?
The CommonSeriesOptions property provides options to customize marker, data label and other properties of all the series in Chart. Except for the Points property, you can customize all the other properties in the series using the CommonSeriesOptions property.
For example, changing marker shape in CommonSeriesOptions changes the marker shape of all the series. To customize marker and other properties for a specific series, values should be provided to the properties of that specific series in the series collection. In general, the values provided to the series in the series collection override the values provided through CommonSeriesOptions.
