Hi Satishkumar,

If your intention is to make some of the points in the live chart to be not visible then it can be done by using the GetEmpty method of the IChartSeriesModel. Kindly take a look at the code snippet below,

public bool GetEmpty(int index)
{

double[] data = (double[])(ydata[index]);

if (data[0] <= 800.0)
return false;
else
{
return true;
}
}
Also take a look at the attached sample.

You can download the sample from the below given webpage link,
http://websamples.syncfusion.com/samples/Chart.Windows/F59681/main.htm

Let me know if I am wrong in getting your requirement.

Thanks & Regards,
Ramya.
