Instead of setting the color to the background, you probably want to
set it to Transparent. This effectively hides the plot since nothing
will be drawn. To choose which plot to set, use the Active Plot
property. You will typically do this in a loop.
Make the top property
the Active Plot, grow the attribute node down and read or write the plot
properties below that. The graph will update at the end of each loop
iteration.
