RadChart has been replaced by RadHtmlChart, Telerik's client-side charting component. If you are considering RadChart for new development, examine the RadHtmlChart documentation and online demos first to see if it will fit your development needs. If you are already using RadChart in your projects, you can migrate to RadHtmlChart by following these articles: Migrating Series, Migrating Axes, Migrating Date Axes, Migrating Databinding, Features parity. Support for RadChart is discontinued as of Q3 2014, but the control will remain in the assembly so it can still be used. We encourage you to use RadHtmlChart for new development.
Series refers to a series of data points displayed in the chart. The RadChart Series object is a collection of ChartSeriesItem objects. The number of series used depends on the type of chart. A Pie chart type only uses a single series. "Stacked" charts like the Stacked Area chart use several series.
Each ChartSeries object contains a collection of ChartSeriesItem objects that contain the actual data points displayed on the chart. You can add data to a series programmatically at run time, at design time in the Properties Window of Visual Studio, declaratively in the ASP.NET HTML markup, or by binding to a data source.
Some key properties for the ChartSeries are:
Appearance: This property contains the common appearance related properties such as Border, Corners, FillStyle and TextAppearance.In addition there are series specific properties including LabelAppearance, LineSeriesAppearance, LegendDisplayMode, BubbleSize and PointMark.
