Area support in WinUI Chart
27 May 20222 minutes to read
Area
AreaSeries is rendered using a collection of line segments connected to form a closed loop area, filled with the specified color.
The following code example initializes the AreaSeries.
<chart:AreaSeries XBindingPath="XValue" YBindingPath="YValue" ItemsSource="{Binding Data}"/>AreaSeries series = new AreaSeries()
{
ItemsSource = new ViewModel().Data,
XBindingPath = "XValue",
YBindingPath = "YValue",
};
chart.Series.Add(series);
Step Area
StepAreaSeries is similar to AreaSeries, but it does not use the shortest distance to connect two data points using Bezier curves. Instead, this ChartSeries uses vertical and horizontal lines to connect the data points in a series forming a step-like progression.
<chart:StepAreaSeries ItemsSource="{Binding Data}" XBindingPath="XValue" YBindingPath="YValue"/>StepAreaSeries series = new StepAreaSeries()
{
ItemsSource = new ViewModel().Data,
XBindingPath = "XValue",
YBindingPath = "YValue",
};
chart.Series.Add(series);
Closed Area
If you wish to draw the open area series (Area with stroke only at the top), SfChart provides IsClosed property. By default, this property is true.
<chart:AreaSeries IsClosed="False" XBindingPath="XValue"
YBindingPath="YValue" ItemsSource="{Binding Data}" />AreaSeries series = new AreaSeries()
{
ItemsSource = new ViewModel().Data,
XBindingPath = "XValue",
YBindingPath = "YValue",
IsClosed = false,
};
chart.Series.Add(series);
