1 min read
An Empty point called as NaN or Not a Null values. WPF Chart (SfChart) provides support to add empty points in chart area. You can show or hide the empty point of chart series by using ShowEmptyPoints property. If you want to differentiate the empty points from normal data points, you need to add the EmptypointStyle property to the series.
XAML
<!--Showing empty points in charts-->
<syncfusion:ColumnSeries ShowEmptyPoints="True" EmptyPointStyle="SymbolAndInterior" XBindingPath="Year" YBindingPath="Count" ItemsSource="{Binding}">
C#
private void MyChart()
{
ColumnSeries series = new ColumnSeries();
series.ShowEmptyPoints = true;
series.EmptyPointStyle = EmptyPointStyle.SymbolAndInterior;
}
