If I use the Group Digital Signals VI to gather digital input signals into busses, and I connect its output to a Digital Waveform Graph, I am able to display the resulting output as busses, or as "busses with lines". When I connect the same output to a Mixed Signal Display, I don't seem to have any ability to display busses at all - the only option seems to be to display all of the inputs as lines. Is there a method by which the busses can be displayed in a Mixed Signal Display?
