Hi,

I want to invoke a label appereance while pressing a point (one of the
input points to chart) in the chart,how do I do it?

How about using the MarksTip tool ?

someone pressed specific point on chart?

You can use the Clicked method, i.e (but in on mouseDown event) :

Code: Select all

private void tChart1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (points1.Clicked(e.X,e.Y) != -1 ) 
{
	//
}
textBox1.Text = points1.Clicked(e.X, e.Y).ToString();
}
