Tooltip when mouse over point (not line)

[Wicket]

I'm using Line series with diamond 'points' in my chart. The chart have several series with several 'points' on each serie.

Now, what I'm interested in doing is giving a tooltip showing the X and Y value of the point when the mouse is above a point (or very close to one), but NOT when the mouse is over the line (between two points).

Bu using the series.Clicked(x, y)... in the MouseMove event, I was able to determine when the mouse is over a line, but as I said, I want to know if the mouse is over a point on the line.

Is this possible?

Hello Andreas,

You could use the ClickableLine property.

Eg.

Code: Select all

private void Form1_Load(object sender, EventArgs e)
{
  line1.Pointer.Visible = true;
  line1.FillSampleValues(10);
  line1.ClickableLine = false;
}

private void tChart1_MouseMove(object sender, MouseEventArgs e)
{
  if (line1.Clicked(e.X, e.Y) != -1)
  {
    //do something ... only triggered over points
  }
  else
  {
    //clear any custom content 
  }
}
