This sample shows the music album sales with the spline series by inverting X and Y axes. Data points are enhanced by a marker and tooltip.
In this example, you can see how to render and configure the spline type charts. A Spline chart uses a curved line to connect points in a data series. Markers are used to represent individual data and its values.
Tooltip is enabled in this example. To see the tooltip in action, hover a point or tap on a point in touch enabled devices.
More information on the spline series can be found in this documentation section.
