The WPF spline area chart is designed for visualizing quantitative data. It is an area chart type that plots a fitted curve through each data point in a series. It is used to represent time-dependent data and show trends in data at equal intervals.
Rotate the spline area chart to plot data in a vertical direction and view data from a different perspective.
The spline area chart handles empty or null data points elegantly.
Customize the color and thickness of the spline area chart using the built-in APIs to make it visually unique.
Use multiple axes to plot different data sets that widely vary from one another.
The WPF spline area chart data points are visualized as marks with the built-in symbols such as cross, square, plus, inverted triangles, hexagon, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons.
