I want to print my Nevron Chart, so, I'm using C#'s PrintDocument PrintPage event. But, my chart do not shown at print preview page. Here is my chart print code. NRectangleF chartBounds = new NRectangleF(headerBounds.Left, headerBounds.Bottom, headerBounds.Width, CompHeight * 8); NChartPrintView chartView = new NChartPrintView(nChartControl.PrintManager, nChartControl.Document, ev.Graphics); chartView.Print(chartBounds); chartView.Dispose(); `NRectangleF chartBounds = new NRectangleF(headerBounds.Left, headerBounds.Bottom, headerBounds.Width, CompHeight * 8); NChartPrintView chartView = new NChartPrintView(nChartControl.PrintManager, nChartControl.Document, ev.Graphics); chartView.Print(chartBounds); chartView.Dispose();` First image is my origin chart at runtime. Second Image is my printview image. When I draw just small data, printview page is well. But, If I draw many datas, my chart are not shown like these images. How can I fix it? 82% of original size (was 614x323) - Click to enlarge Tags chart print

To save the control state you can use: nChartControl1.Serializer.SaveControlStateToFile("c:\\temp\\chartstate.xml", Nevron.Serialization.PersistencyFormat.XML, null); Let us know if you meet any problems... Best Regards, Nevron Support Team

We investigated the issue and indeed the control is printing properly, but only when the amount of data is low. We suspect this is caused by a problem in Windows and the workaround is to create a high res raster, which in turn can be printed: Bitmap bitmap = new Bitmap(2000, 2000, printerGraphics); nChartControl1.ImageExporter.RenderToBitmap(bitmap, false); // you can draw the bitmap to the printerGraphics here bitmap.Dispose(); We hope this helps - let us know if you meet any problems or have any questions. Best Regards, Nevron Support Team
