In this example, you can see how to render and configure a spline chart. The spline chart uses a smooth, curved line to connect points in a data series. The ChartMarker represent individual data points and their values, while the ChartCrosshairSettings enhances data tracking by displaying exact values at the nearest data point when hovering over the chart.Additionally, the HighlightCategory property in the crosshair highlights the entire category range on hover.

Tooltip is enabled in this example. To see a tooltip in action, hover over or tap on the chart.

More information about the spline series can be found in this documentation section.
