Hello asche,
I justed tested it:
I can make everything transparent, so that you only see the text and the line of the legend...
I only used the color tool to do so.
Oh wait: to remove the box around the line style of the legend you have to make the border of the
graph display transparent. It seems to use the same setting: graph fore- and background is the same
like legend plot style... I made a picture to show this behaviour.
So it seems that NI has to change a setting in LabView for the next version...
Best regards,
GerdW
