Populate Data

When you provide data to RangeNavigator, it produces limited set of data. You can populate the RangeNavigator with data using the dataSource and series properties.

Add series to the RangeNavigator

The Series property provides access to a collection of all series that are defined explicitly within a RangeNavigator control. Each series is assigned with type and name. It contains collection of data point, each point contains x value and y values. You can add data points to the series through dataSource property.

Animation can be enabled by setting e-enableanimation property as true and the series color and opacity can be customized by using e-fill and e-opacity property in series.
