Overview

The WPF spline range area chart is used to display continuous data points as a set of splines that vary between high and low values over intervals of time and across different categories.

Beautiful WPF spline range area chart.


Key features

The WPF spline range area chart with an empty or null point.

Empty/Null point chart

Empty or null data points are elegantly handled in spline range area charts.

Shows the different spline range area chart types.

Spline type

Four different types of rendering: natural, monotonic, cardinal, and clamped.

Shows the WPF vertical spline range area chart.

Vertical spline range area chart

Rotate the spline range area chart to plot data vertically and view the data from a different perspective.
