DPlot

When using operate on Y from the edit menu (v2.1.1.9), I've found that all of the reference lines are also getting operated on even when I only select one curve as the target. Haven't noticed this before but I don't use this feature regularly enough to say how long it's been doing this...

Richard,
Thanks, that's a mistake. What it should be doing (and will in the next release) is applying that transform to Y reference lines only if all curves are being operated on.
