Spline chart

Hi,
The below is the code I am using to plot a line chart with the chart type as Spline.. This works fine when there are 10-15 points. But my curve has 350 points and the spline looks more like a Line curve...


ChartDataBindModel model1 = new ChartDataBindModel(ds,"");
model1.XIndex = 0;
model1.YIndexes = new int[]{2};

ChartSeries series1 = this.Chart.Model.NewSeries("1", ChartSeriesType.Spline);
series1.SeriesModelImpl = model1;

Please advice
Thanks
Tom

Hi Tom,

Thanks for your detailed explanation.

The scatter chart type having special property for adjusting the spline tension. Please use the ScatterSpline chart and you can get the smooth curve by adjusting the ScatterSplineTension property. Please refer to the following code snippet.

[ C# ]
series1.ScatterConnectType = ScatterConnectType.Spline;
series1.ScatterSplineTension = 0.2;
series1.Style.Symbol.Size = new Size(0, 0);

Please have a look at this sample and let me know if this helps you.
