public Boolean IncludeIndex {get; set;}
Remarks
Default: False
Whether or not to include the Index of each point in the output Seriesdata. For Series data added with the Add method the Index values will equal the X values as the Add method generates X values against an input of only Y values (for eg. a Line, Bar or Area Series). For data added as XY values (eg. with AddXY), then the output Seriesdata will include those X and Y values and the Index column (if enabled with the IncludeIndex property) will contain an list of point indexes which will be a sequential count of point indices.
