ColumnSeries<T, D> class

This class has the properties of the column series.

To render a column chart, create an instance of ColumnSeries, and add it to the series collection property of SfCartesianChart. The column series is a rectangular column with heights or lengths proportional to the values that they represent. it has the spacing property to separate the column.

Provide the options of color, opacity, border color, and border width to customize the appearance.
