Click event on a series in chartFX

[arvindragavan]

Hello,

Im using chartFx to display a bar chart, on click of a perticular series in the chart i want to display the selected details in a second chart throw C# code , But i am not able to find any event in which i can populate the second chart with the data on click of the series. for now i am getting the data for which the series is when the tool tip of the series is opened . Is there any other way to do it. Kindly help me to solve it.

Thank You

You should be able to attach an event handler to the Chart.MouseClick event. In the HitTestEventArgs we include information about the series and point index the user clicked as well as the underlying CLR object (DataItem property) represented by the marker.

Hello, you helped me with an example of this on a Pie Chart. It worked for a while but has sporadically started throwing exceptions when the chart is clicked. Here is my code and the exception. 

 Please help!private void chrtUnitsByProduct_MouseClick(object sender, HitTestEventArgs e)

{

if ((e.Point >= 0) && (e.Series >= 0) && (SDBox.SelectedValue != null))

{

// Change third chart ItemsSource here using e.DataItemdProduct p = (dProduct)e.DataItem;if (p.Channel != "All Channels")

{

// MessageBox.Show(c.Channel);DataAccess dao;

dao = (

DataAccess)App.Current.FindResource("dao");chrtUnitsByRegion.ItemsSource = dao.dGetDataByRegionForProductChannel((Int16)SDBox.SelectedValue, p.Product, p.Channel);

// <TextBlock Text="{Binding Path=DataItem.channel}" Background="Transparent" Foreground="{StaticResource FontBrush}" FontWeight="Bold" FontFamily="Calbiri" FontSize="13" HorizontalAlignment="Center"/> TextBlock tb = new TextBlock();

tb.Text =

"Channel: " + p.Channel + ", " + p.Product;tb.Background = Brushes.Transparent;

tb.Foreground = (

LinearGradientBrush)App.Current.FindResource("FontBrush");tb.FontWeight = FontWeights.Bold;tb.FontFamily = new FontFamily("Calbiri");

tb.FontSize = 11;

tb.HorizontalAlignment = HorizontalAlignment.Center;

chrtUnitsByRegion.Titles[1].Content = tb;

}

}

}
