      • 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.

        geom - context geom
        Returns:
        geom to use for data interpretation, the same or similar to the input
