How to manage the empty values in WPF Chart (SfChart)?
This article explains how to manage empty points, often referred to as NaN (Not a Number) in WPF Chart (SfChart). Syncfusion® SfChart provides functionality to show or hide empty points in the chart area using specific properties.
Implementation Details:
In a WPF Chart, you can manage the display of empty points within a series by using the ShowEmptyPoints property. To visually differentiate empty points from regular data points, utilize the EmptyPointStyle property.
XAML Example:
<!--Showing empty points in charts-->
<syncfusion:ColumnSeries ShowEmptyPoints="True" EmptyPointStyle="SymbolAndInterior" XBindingPath="Year" YBindingPath="Count" ItemsSource="{Binding}">
C# Example:
private void MyChart()
{
ColumnSeries series = new ColumnSeries();
series.ShowEmptyPoints = true;
series.EmptyPointStyle = EmptyPointStyle.SymbolAndInterior;
}
Output:
