Question

So I’ve made this range bar chart with the MS Chart Control. I have a question:

How can I implement an event handler for when the user clicks on red colour? I can’t see one anywhere.

I am uploading the sample graph here

I want to show another graph if you click on red colour on this graph

so how can i create click event handler for this one

Answer 1

See find the region part of live using c# for similar question … within the click handler do this

var pos = e.Location;
var results = chart1.HitTest(pos.X, pos.Y, false, ChartElementType.DataPoint);
foreach (var result in results)
{
  if (result.ChartElementType == ChartElementType.DataPoint)
  {
    if (result.Series.Points[result.PointIndex].Color == Color.Red)
    {
       Console.WriteLine("success?");
    }
  }
}  

Note that color could be null on a particular point but appear red on the graph (it would be obtained from the series). As long as you manually set the color on the clickable points, that will work, but you may want to think whether the color is the thing you should be testing.
