I want to change the color of the NON plotting area of a waveform graph indicator in 6i. I want to do this programmatically. I know how to programmatically change the color of the plotting area, tick marks, the text colors of markers, labels etc using property nodes. My question is what about the color of the area surrounding the plotting area comprising the EDGE of the graph. Is there something staring straight at me that I don't see? Thanks in advance for your help.
