How to add a background image behind the graph plot area

Hi all,
I would like to know if there is a way to add a background image (*.png)

behind the graph plot area?

What I would like to accomplish is that during an acquisition measurement you can see

if the result values are out of specs or not.

I have found this link:
http://zone.ni.com/reference/en-XX/help/371361R-01/lvconcepts/customizing_graphs_and_charts/

But it’s way to difficult for me, I don’t understand it, is there a more simpler way to just

add a picture (*.png) behind the graph plot area?

I want something like this, were the blue area is right zone
everything outside this erea is wrong,

Instead of adding an image (which gets messed up as soon as your graph scales change) plot the upper and lower limits as data for Plots 3&4.  You can set Plot 3 to fill to Plot 4 and this way it will scale with the rest of your data also.

It's not visually quite as nice, but it's more robust and adapts better to UI changes.

Thank you Intaris for your fast reply,

Looks a fine solution for me, I'm going to try it!

Best regards,
