Hi,
I am trying to plot a multi-y graph and I am getting a NullReferenceException when I try to add the series to the chart control. The code is very simple:

ChartSeries series;
for(int i=0;i<3;i++)
{
series = this.ChartWebControl1.Model.NewSeries("MultiY" + i.ToString(), ChartSeriesType.Line);

Random autoRand = new Random();
for (int j=0; j<100; j++)
{
series.Points.Add(j, j * autoRand.Next());
}

this.ChartWebControl1.Series.Add(series);
}

I do have a Pie Chart and Bar Chart working just fine with similar setups.

I did notice that while tracing the code I get a "series.BackColor threw an exception of type 'System.IndexOutOfRangeException'"

Thanks.
David.

Hi David,

Thank you for your interest in Syncfusion Products.

I am afraid I was unable to reproduce the issue. Please refer the sample in this link
http://websamples.syncfusion.com/samples/Chart.Web/6.1.0.34/72390/main.htm where the code you have given renders Line Chart without throwing an exception.

Can you reproduce the issue in this sample so that we can work in depth and send a better solution?

Regards,
Anupama
