      • setSeriesGroup

        public void setSeriesGroup​(Field field)
        Creates a series group on this field. This group is for sorting and consolidating records with same values on the group axis, i.e. the x axis by PlotOrientation.VERTICAL. The series group handles data grouped by the category group. To change the sort order of the data in this group, get this with getSeriesGroup() and use the Group properties. SummaryField, SpecialField and GroupField are unsupported field types.
        Parameters:
        field - (null not permitted)
        Throws:
        java.lang.IllegalArgumentException - if field is null or has an unsupported field type.
