How to save the waveform graph to the image file?

[ThunderBird]

Hi,
I found we can use right-click 'waveform graph' -> Data Operations -> Export simplified images...
to save the waveform to image file. Can I just use one button to implement this? I mean when I click this button, the 'Export simplified images...' window can pop out. I am just don't want the user to right-click ... then choose ... then..., just one button is better.
Thanks for your answer.

Hi TBird

I can't see this operation. Are you using LV 7.1?

Nevertheless I assume that this operation may be available in the invoke-node. This is similar to the property-node but with methods.
Just right-click the graph-terminal on the block-diagram and select create->invoke node. After creating you can right-click it and select methods->...

But I am not sure if this works - just have a try.

Hope this helps.

Use an invoke node for your graph with "get image".

I made a quick example that saves a FP graph to a PNG file (LabVIEW 7.0). Modify as needed.

Hi,
You code works well but the result is different with using " Export simplified images... ", you can try that.
After using right-click and " Export simplified images... ", we get a white background clear curve. With you code we just get a copy of the LabVIEW interface.
I am using LabVIEW 7.1.

Please look at the attache result if I use " Export simplified images... "
Thanks.

Simply wire a "1" (Instead of the current "24") to the image depth input of the property node.
