how to get the clear graph image

[hugoliang]

I have designed a printcontrol vi.When the curve shows in the waveform graph in the front panel,the image is clear to see.But when I use a printer to print the report ,the waveform graph is not clear enough.I figured out a scheme like this:I have first saved the waveform graph to a  image ,then wanted to use the append image to report subvi to get a clearer image .But the vi runs,there is always an error . I don't know where the problem is .The vi is attached to the enclosure.How can i get a clear image in a printed report? THANKS  IN ADVANCE FOR YOUR HELP!

Worked for me. What was the format of the image you are trying to append?

Append Image to Report works for .bmp, .gif, .wmf, .emf, and .jpg image files, but not .png files.

Thanks, Bill. I forgot that it wont work for png files.

I have noticed the rule that Append Image to Report works for .bmp, .gif, .wmf, .emf, and .jpg image files, but not .png files.The format of image which I try to append to report is .jpg.But when I run the vi ,an error will occur.The picture is attached to the enclosure. THANKS  FOR YOUR HELP!

The  attached image is definitely a .png file. I think you ve modified its extension, thats why it gives error.

Simply changing the file extension wont work with the VIs.

While during saving, you ve to save it as a .jpg file...

Try to download it from your message, it gets stored as a .png. Thats how I found its nature.
