Range series are created for values data groupings displayed in combo charts, by setting the Series Type to Range. The Range Series can display 2D or 3D shapes defined by the begin / end values of their bounding boxes. It can be used for display of histograms, bars with custom sizes, 3D ranges etc.
Range series always support the Y1, Y2 and Label data point values. If the Combo Chart Subtype is set to XY Scatter, the series will also accept X1 and X2 data point values. Similarly when the Combo Chart Subtype is set to XYZ Scatter the series will also accept Z1 and Z2 data point values.
