Hi,

what is the problem you are seeing exactly?
If you post
- a VI with a graph on it
- an image where you copied the Graph from the VI above that shows you lost color info

we might be able to help you.

Hi Alessio,
I'd like to store a Graph image in the Clipboard RUN TIME (pressing a button), an then for instance copy it in a PowerPoint page or something else by pressing Ctrl+V. I saw that there is the possibility to copy the graph in the clipboard but in a simplified image "Export simplified Image..." see picture "From LV.bmp". My target is to have the picture like "target.bmp".

An example graph is in the attached vi.

Many thanks in advance.

Neona,

If you absolutely must do this in response to a user clicking a front-panel button, as suggested in your attached example, then you'll need to hunt down some code. Programmatically, the built-in LabVIEW functions will take you only so far as getting the full-color image data (Right-click on your graph and choose Create >> Invoke Node, then select the Get Image method from that node), but not sending it to the clipboard.

George Zou has created VIs to do this exact thing (send image data from LabVIEW to the clipboard), but I haven't used them and I'm fairly sure they are not free. Plus, I think his main site is down right at the moment. See this thread.

There's a much easier solution. If you're willing to ask your users to right-click the graph and choose Copy Data at run-time, then that will copy a nice full-color image of the graph to the clipboard, and you can paste it into PPT, etc, as you desire. It's not quite clicking a button, but it's comparably easy.

Hi John,
many thanks for your appropriate response, I'll use the pop-up menu of the graph.

Best Regards

Neona, I was interested in that option (.emf graph).
Please, ask NI to implement that option in next Labview version( Labview zone- Wishes for next version, I guess). I did. If there are many requests, they will do that. If now that functionality is possible in a pop-up menu, should be quite easy a programmatically implemantation.

Hi Neona
This is the answer for your post and mine. After some googling, I found the solution to copy a graph to clipboard.
using 24 bits color, the graph is as in labview. Using 1 bit, the graph is a simplified b/w picture.
this is the link: http://labview.citeng.com/pagesNL/labview/app.aspx
the file is "ctrlrefs.zip". Needs some work to update for Lv 7, but runs fine.

Hope it helps
