RadChart Error

[Konrad]

Hi,

I have a strange situation where working splines or lines in RadChart gives me the following error on Mono:

(It works fine on IIS7)

Invalid parameter passed. Number of points and types must be same.

Description: HTTP 500. Error processing request.

Stack Trace:

System.ArgumentException: Invalid parameter passed. Number of points and types must be same. at System.Drawing.Drawing2D.GraphicsPath..ctor (System.Drawing.PointF[] pts, System.Byte[] types, FillMode fillMode) [0x00000] at System.Drawing.Drawing2D.GraphicsPath..ctor (System.Drawing.PointF[] pts, System.Byte[] types) [0x00000] at (wrapper remoting-invoke-with-check) System.Drawing.Drawing2D.GraphicsPath:.ctor (System.Drawing.PointF[],byte[]) at Telerik.Charting.RenderEngine.DrawLines (Telerik.Charting.ChartSeries series, Int32 index, System.Drawing.PointF[] points) [0x00000] at Telerik.Charting.RenderEngine.RenderLineSeries (Telerik.Charting.ChartSeries series, Int32 index) [0x00000] at Telerik.Charting.RenderEngine.Render (Telerik.Charting.ChartSeries series, Int32 index) [0x00000] at Telerik.Charting.RenderEngine.RenderPlotAreaElements (Boolean withGrid, Boolean withTicks) [0x00000] at Telerik.Charting.RenderEngine.Render (IContainer element) [0x00000] at Telerik.Charting.RenderEngine.Render (Boolean shouldClone) [0x00000] at Telerik.Charting.Chart.GetImage (Int32 width, Int32 height) [0x00000]

Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 2.0.50727.1433

My code is as follows:

	ChartSeries chartSeries;
	radChart.Series.Clear();
	radChart.PlotArea.XAxis.Clear();
	radChart.PlotArea.XAxis.AutoScale = false;
	radChart.PlotArea.XAxis.LayoutMode = ChartAxisLayoutMode.Between;
	radChart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 270;
	radChart.PlotArea.Appearance.Dimensions.Margins.Bottom = Telerik.Charting.Styles.Unit.Percentage(20);
	radChart.PlotArea.XAxis.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Top;
	radChart.PlotArea.YAxis.IsLogarithmic = true;
	chartSeries = new ChartSeries("test", ChartSeriesType.Spline);
	radChart.Series.Add(chartSeries);
	ChartSeriesItem chartSeriesItem = new ChartSeriesItem(12);
	chartSeries.Items.Add(chartSeriesItem);
	chartSeriesItem = new ChartSeriesItem(43);
	chartSeries.Items.Add(chartSeriesItem);
	chartSeriesItem = new ChartSeriesItem(65);
	chartSeries.Items.Add(chartSeriesItem);

Anyone have any ideas?

Thanks,

Konrad

Hello Konrad,

It seems the Mono platform has a problem with the implementation of some specific graphics scenarios (the exception is triggered by their GraphicsPath implementation).

Unfortunately as the scenario works correctly with the regular .Net platform, there is not much we can do right now but forward your feedback to the Mono developers and hope that they will be able to resolve the problem so Mono behaves correctly under the same circumstances as well.
