Namespace: chartRegistry

dc. chartRegistry

The dc.chartRegistry object maintains sets of all instantiated dc.js charts under named groups and the default group.

A chart group often corresponds to a crossfilter instance. It specifies the set of charts which should be updated when a filter changes on one of the charts or when the global functions dc.filterAll, dc.refocusAll, dc.renderAll, dc.redrawAll, or chart functions baseMixin.renderGroup, baseMixin.redrawGroup are called.
