I spent some time trying to learn how to use the ‘signaldisplay’ widget, and for the life of me, I couldn’t figure out why nothing was displaying. This was at least until I figured out that you had to set the “colour” parameter. I guess I was just assuming that this parameter would have a default, but it appears that it has to be set explicitly to see the signal in the display. Might it be possible to add this to the documentation so that we don’t beat our heads against this brick wall?

Good call. Fixed and pushed to git
