How to Hide the Series with WPF Chart Legend?
WPF Chart provides the ability to hide series using the ChartLegend. This functionality can be achieved by utilizing the ToggleSeriesVisibility or CheckBoxVisibility properties of the ChartLegend. This article explains in detail how to hide the series in the WPF Chart through legend.
Solution: 1 You can use the ToggleSeriesVisibility property of the chart legend to disable a series in WPF Chart by toggling the legend item.
[Xaml]
<chart:SfChart>
…
<chart:SfChart.Legend>
<chart:ChartLegend ToggleSeriesVisibility="True">
<chart:ChartLegend.Header>
<Label FontSize="15" Content="Subjects" FontWeight="Bold"
VerticalAlignment="Center" HorizontalAlignment="Center" />
</chart:ChartLegend.Header>
</chart:ChartLegend>
</chart:SfChart.Legend>
<chart:ColumnSeries Label="Biology" ItemsSource="{Binding MathsData}"
XBindingPath="StudentName" YBindingPath="Mark" >
</chart:ColumnSeries>
<chart:ColumnSeries Label="Chemistry" ItemsSource="{Binding PhysicsData}"
YBindingPath="Mark" XBindingPath="StudentName" >
</chart:ColumnSeries>
</chart:SfChart>
[C#]
SfChart chart = new SfChart();
…
ChartLegend legend = new ChartLegend()
{
ToggleSeriesVisibility= true,
Header = new Label()
{
Content = "Subjects" FontWeight = FontWeights.Bold, FontSize = 15
HorizontalAlignment = HorizontalAlignment.Center, VerticalAlignment = VerticalAlignment.Center,
}
};
ColumnSeries series1 = new ColumnSeries()
{
XBindingPath = "StudentName", YBindingPath = "Mark",
ItemsSource = (new LegendsViewModel()).MathsData, Label = "Chemistry",
};
ColumnSeries series2 = new ColumnSeries()
{
XBindingPath = "StudentName", YBindingPath = "Mark",
ItemsSource = (new LegendsViewModel()).PhysicsData, Label = "Biology",
};
chart.Series.Add(series1);
chart.Series.Add(series2);
chart.Legend = legend;
this.Content = chart;

<chart:SfChart> … <chart:SfChart.Legend> <chart:ChartLegend CheckBoxVisibility="Visible"> <chart:ChartLegend.Header> <Label FontSize="15" Content="Subjects" FontWeight="Bold" VerticalAlignment="Center" HorizontalAlignment="Center" /> </chart:ChartLegend.Header> </chart:ChartLegend> </chart:SfChart.Legend> … </chart:SfChart>

ChartLegend legend = new ChartLegend()
{
CheckBoxVisibility = Visibility.Visible,
Header = new Label()
{
Content = "Subjects" FontWeight = FontWeights.Bold, FontSize = 15
HorizontalAlignment = HorizontalAlignment.Center, VerticalAlignment = VerticalAlignment.Center,
}
};
