I just switched to Version 5.1.0.51 from Version 4.4.0.51. I got an "Out Of Memery" problem with ChartType Line. The same code worked in the previous version. If I use other ChartTypes, I have no problem. Please see the attached file for the error message. Anyone have this problem? Please help me. Thanks.

Hi Bailin,

Thank you for your interest in Syncfusion Products.

I tried to reproduce the condition that you have mentioned here using the below code snippet but I was not able to reproduce it.


private void Form1_Load(object sender, EventArgs e)
{
ChartSeries series = this.chartControl1.Model.NewSeries("MySeries", ChartSeriesType.Line);
series.Points.Add(1, 9);
series.Points.Add(3, 6);
series.Points.Add(5, 12);
series.Points.Add(7, 2);
series.Points.Add(9, 7);
this.chartControl1.Series.Add(series);
}

Could you please provide me with a sample which reproduces the condition that you have mentioned here, so that it would help me in analyzing this issue?

Thanks & Regards,
Ramya.

Ramya,

Thank you very much for your quick response. It took me a while to find what causes the problem. To reproduce this problem, you need to add two points whiach are identical, for example:
series.Points.Add(1, 9); series.Points.Add(3, 6); series.Points.Add(5, 12); series.Points.Add(5, 12); series.Points.Add(7, 2); series.Points.Add(9, 7);

You may wonder why I need two points with the same X and Y values, but my application sometime requires this kind of data. It worked in the previous version (4.4.0.51). It seems this version (5.1.0.51) eliminates any array space if a point is identical to another. It only happens when 2-D Line ChartSeriesType is used. If 3-D Line is used, the problem is gone. Hope the information will be helpful.
