Right click on a control/indicator and select Create>Invoke Node>Create Image. Right click again on the control/indicator and select Create>Reference. Wire the reference to the method and wire the Image Data to the Write JPEG (PNG, BMP) function.

thanks so much for quick response.it is really helpful!

in LabVIEW 8.6 I found "get image" but I did not find "create image."

it looks like the attachment.

there is no pick to connect to "new picture"

I ran it and found that it save the black plot.

Could you please let me know how to save the final picture?

Thanks very much

Sorry about the typo. The Get Image is correct.

I don't know what you mean by 'there is no pick to connect to "new picture"'. In the quick image that I did, I did not do any dataflow to ensure that the Get Image method is run after you write the data to it. Could be that is your problem.

thanks for quick response, Dennis,

My question is that "get image" function saves the figure before the program runs.

For example, I put some data in the table of the attachment2 code and run it. The image saved is as the attachment1 with no data info on it.

I hope to save the image with data info.

Please let me know if my explanation is not clear, and please give me some advice.

thanks

As I said, there is no dataflow in the quick example. You should add some. Maybe place the method inside a single sequence structure and wire the new picture to it.
