When I print a graph control the traces are not there.

Hi,
When printing a graph control, the outline and control print just fine, however, the traces that are visable when on the screen do not print. I also tried two different printers.

Try making the lines thicker and see if that helps. Also, try Bitmap printing mode (SetPrintAttribute).

Chris,
Thanks for the reply, however, no help. I changed to a fat line, even to a scatter plot. Even though they show up great on the screen, the traces only will not print. Grids, labels, numbers etc all print fine. Even tried a color laser printer to see if it was that.
Help..

Chris,
I went to the support area, and there I found the answer. I was doing something wrong. I had my graphs set to discard data and not retain it. The document is 0HFDSKZL . Thanks for your help.

Did you try the bitmap printing mode? (SetPrintAttribute). Bitmap printing sends an image to the printer instead of GDI printing instructions. Also, this may be a stupid question, but you are sure you aren't printing before the graph is updated. Try the attached program to see if it prints OK.

Chris,
Your graphs print just fine. Mine still do not. I have a print button on my panel just like yours. I call the same PrintCtrl command that you do and I am printing the control that I already have visible. I also tried Bitmap printing.. Still no help.
Everything is there but the traces....

I have no good guesses for you. You may want to have support see if they can look at your program and find the problem. Contact them at http://www.ni.com/ask.
