Each DataSeries in a chart is composed of PlotElement objects that represent each individual symbol, connector, area, pie slice, etc in the series. The specific type of PlotElement depends on the chart type.

You can add animations to your charts by attaching Storyboard objects to the plot elements. This is usually done in response to the DataSeries.PlotElementLoaded event, which fires after the PlotElement objects have been created and added to the data series.
