Hi.
I create an ultrachart and then call the RenderPDFFriendlyGraphics function to render the chart to a pdf report. The code looks like this:
ICanvas canvas = newFlow.AddCanvas();
canvas.Width = new FixedWidth(210);
canvas.Height = new FixedHeight(170);
Graphics g = canvas.CreateGraphics();
ultraChart1.RenderPdfFriendlyGraphics(g);
The RenderPDFFriendlyGraphics takes a long time to execute. Is this normal? My chart consists of about 50 series each of 175 points.
Hello Sudnya,
Please answer the following questions for me so I can better assist you.
I am using NetAdvantage Windows Forms 2010.2 and visual Studio 2010.
I've done some more testing and it appears the delay is happening because of the amount of data being plotted. You can verify this yourself by commenting out the second loop in the CreateCharts() method in your sample. You'll see that the amount of time taken is just about halved.
OK. I am working with medical software and this will be the minimum amount of data I am plotting per graph. Plus I am plotting 6 such graphs.
So that probably means using the infragistics chart in this situation is not going to deliver the results in a resonable amount of time. Do you have any other suggestions as to what I can use.
Thanks.
Sudnya
It might be more feasible for you to call DrawToBitmap() and then insert that bitmap into the document.
Hi Dave.
Thats what we currently do in the application. However, when the bitmap is plotted on a PDF and the document is zoomed the bitmap loses its resolution and looks grainy. This was the reason I was exploring other options and came across the RenderPDFFriendlyGraphics function.
So using the bitmap is not really an option.
I've submitted this issue to our engineers for them to research. I've created a private support case so you can be notified of the results of their research.
Sorry for the delay but I found the cause of the issue and it is currently being verified and if all goes well a fix will be available in the next Service Release. Let me know if you see anything else performance related to the chart -> pdf process but I think you'll be pleasantly surprised by the speed of the process now.
