double gog_chart_map_2D_derivative_to_view (GogChartMap *map,double deriv,double x,double y);
Converts a 2D slope from data space to canvas space. It is only implemented for xy maps.
void gog_chart_map_2D_to_view (GogChartMap *map,double x,double y,double *u,double *v);
Converts a 2D coordinate from data space to canvas space.
GogAxisMap * gog_chart_map_get_axis_map (GogChartMap *map,unsigned int index);
Convenience function which returns one of the associated axis_map.
Valid values are in range [0..2].
GogChartMapPolarData *
gog_chart_map_get_polar_parms (GogChartMap *map);
Convenience function for retrieving data related to polar plot layout.
gboolean
gog_chart_map_is_valid (GogChartMap *map);
Tests if map
 was correctly initializied, i.e. if all associated axis_map
are valid (see gog_axis_map_is_valid() ).

GogChartMap * gog_chart_map_new (GogChart *chart,GogViewAllocation const *area,GogAxis *axis0,GogAxis *axis1,GogAxis *axis2,gboolean fill_area);
Creates a new GogChartMap, used for conversion from data space to canvas space.
