Remarks

This class exposes all of the properties, methods and events of the Chart Web control.

Two important properties of the Chart class are the Series and ChartAreas properties, both of which are collection properties. The Series collection property stores Series objects, which are used to store data that is to be displayed, along with attributes of that data. The ChartAreas collection property stores ChartArea objects, which are primarily used to draw one or more charts using one set of axes.
