如何清除点图中的标绘值？

Question

In my C# application ,using a points chart that is working fine. But if I try to clear all plotted points it is not clearing. How to do this?

Refer below the code,

series1.Points.AddXY(1, 10);//Plotting the points in chart
series2.Points.AddXY(2, 20);
chart1.Series.Clear(); //I tried to clear using this code

If i tried the above code for clear , it is removing entire chart but I want to clear only the plotted points.

Answer 1

To clear all the points in the series:

chart1.Series[0].Points.Clear();

To remove the first point in the series:

chart1.Series[0].Points.RemoveAt(0);

To clear all the points in all series:

foreach(var series in chart1.Series) 
{
    series.Points.Clear();
}
