Hello,

One way to go is to hide the PlaneXY when the chart loads:

private void chart1_Loaded(object sender, RoutedEventArgs e)
{
  PlaneXY planeXY = Telerik.Windows.Controls.ChildrenOfTypeExtensions.ChildrenOfType<PlaneXY>((RadChart)sender).First();
  planeXY.Visibility = Visibility.Collapsed;
}

Hello, thanks for your reply.

Unfortunately your code is giving me a crash, I guess is because planeXY is null and I don't know why.
My telerik version is 2016.1.112.1050, Below I have posted my xaml, so could you please check it.

Thanks in advance

Hello,

What do you mean that the code is giving you a crash? Is it indeed a null reference exception? Perhaps in this case you can do the same in a LayoutUpdated.

private void chart1_Loaded(object sender, RoutedEventArgs e)
{
 this.chart1.LayoutUpdated += this.chart1_LayoutUpdated;
}

private void chart1_LayoutUpdated(object sender, System.EventArgs e)
{
 PlaneXY planeXY = Telerik.Windows.Controls.ChildrenOfTypeExtensions.ChildrenOfType<PlaneXY>(this.chart1).FirstOrDefault();
 if (planeXY != null)
 {
  planeXY.Visibility = Visibility.Collapsed;
  this.chart1.LayoutUpdated -= this.chart1_LayoutUpdated;
 }
}
