plot legend color

[knapkerd]

During data acquisition I am checking the values of certain data to make sure they are in the allowable range.  I am plotting several of these "checked" values on the same waveform graph.  I was wondering if there is a way to change the color of the background of the plot legend (as seen in the picture) while the program is running?  I would also like to be able to change each one independently.

I have seen ways of changing the color of the waveform graph colors before running and I have also seen the use of a multicolumn listbox for something similar, but I would like to use the legend itself.  I have searched and as of a year or so ago it appears as if there is no way to do this.  I was just wondering if this had changed.

Thanks for your help.

Afaik, you cannot use the plot legend itself to change the background color but you can have a front panel color box control and use this to write to a property node. You cannot have different background because you have a single graph and obviously, only one background color. For displaying data in and out of tolererance, have you seen the example called Envelope? It uses the new Plot Images property.

Thanks for the quick reply.  I think I may go with the colorbox option.  I looked at the envelope example.  It would be useful to display in this way, but it may not be feasible because the extra rendering would slow down my data acquisition.

Again thanks for the help.
