        Returns:
        number of sets of positional coordinates

      • getExtraCoords

        public Coord[] getExtraCoords()
        Description copied from interface: ShapeForm
        Returns data coordinates additional to the basic position which are required to plot a point.

      • adjustGeom

        public DataGeom adjustGeom​(DataGeom geom)
        Description copied from interface: ShapeForm
        Provides a DataGeom to be used by the layer this form makes, given a DataGeom that characterises the plotting environment. The output should be similar to the input, for instance implementing the same plotType-specific DataGeom subtype.

        In most cases the supplied instance can be returned unchanged, but instances with special requirements may want to adjust how the data is interpreted.

        Specified by:
        adjustGeom in interface ShapeForm
        Parameters:
        geom - context geom
        Returns:
        geom to use for data interpretation, the same or similar to the input

        Specified by:
        createOutliner in interface ShapeForm
        Parameters:
        config - configuration map from which values for this form's config keys will be extracted
        Returns:
        new outliner object
