Area Chart in WinUI Charts (SfCartesianChart)

Area Chart

The WinUI Area Chart is rendered by using a collection of line segments connected to form a closed loop area, filled with the specified color. To render a area chart, create an instance of AreaSeries and add it to the Series collection property of the chart.

Spline Area Chart

The SplineAreaSeries connects a series of data points using smooth bezier line curves, with the underlying areas filled.

SfCartesianChart chart = new SfCartesianChart();

    ItemsSource = new ViewModel().Data,
    XBindingPath = "Demand",

Step Area Chart

The StepAreaSeries is similar to AreaSeries, but it does not use the shortest distance to connect the two data points using bezier curves. Instead, this series uses vertical and horizontal lines to connect the data points in a series forming a step-like progression.

        <chart:StepAreaSeries XBindingPath="XValue" 
							  YBindingPath="YValue" 
							  ItemsSource="{Binding Data}"/> 
    </chart:SfCartesianChart.Series>

SfCartesianChart chart = new SfCartesianChart();
CategoryAxis xAxis = new CategoryAxis();
chart.XAxes.Add(xAxis);
NumericalAxis yAxis = new NumericalAxis();
chart.YAxes.Add(yAxis);

StepAreaSeries series = new StepAreaSeries()

    XBindingPath = "XValue",
    YBindingPath = "YValue",

chart.Series.Add(series);
