The WPF spline chart resembles a line chart, but instead of connecting the data points with straight lines, the data points are connected by smooth Bezier curves.
WPF Spline Chart documentation
Use Four types of rendering: natural, monotonic, cardinal, and clamped.
Rotate the spline chart to plot data in a vertical direction and view it from a different perspective.
Empty or null data points are elegantly handled in spline charts.
Use multiple axes to plot different data sets that widely vary from one another.
Data points are visualized as marks with built-in symbols: crosses, squares, pluses, inverted triangles, hexagons, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons.
Easily get started with the WPF Spline Chart using a few simple lines of C# code example as demonstrated below,
