hello I ' m using Nevron . NET Chart at . net 5 . 0 , winform . However , I have some questions . 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

Hi , Please send the state of the control for review . 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,

Hi Yunhyungjeon , Thank you for sending the save file . 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,
