I have a graph with multiple series, but I want the user to only be able to select a single point on the graph at a time. This means that if the user has selected a point in one series, and then selectes a point in another series, the first point need to be deselected. I've tried to programatically set the SelectedIndex of all the other series to -1 when a point is selected, but that doesn't seem to have had an effect. Have I missed a step, or is there another way to ensure that only a single point is selected

<chart:SfChart x:Name="chart"
SelectionChanging="chart_SelectionChanging">
…
<chart:SfChart.Behaviors> <chart:ChartSelectionBehavior/>
</chart:SfChart.Behaviors>
</chart:SfChart> |
|
private void chart_SelectionChanging(object sender, ChartSelectionChangingEventArgs e)
{
foreach (var series in chart.Series)
{
//Check condition based on the series added in Chart SeriesCollection
if (series != e.SelectedSeries as LineSeries)
{
(series as LineSeries).SelectedIndex = -1;
}
}
} |
Thanks, that fixed it.
