We have custom graphs that display data from multiple locations, but none of the data is a higher priority than the other. With channel 1 being filled it really makes a mess of the graph in this particular situation.
Is there a way to disabled filled graph mode? If not, could you add an option under sensor display for "Show channels independently (no fill)".
Along those same lines, is there a way to have all channels on a custom graph display their Max and Min values?
