I have graphs with many data sets. My goal is to make them all distinguishable, even in grey-scale view. The problem is, though, that some colors are too light to be seen in greyscale, but I would hate to change them in this late stage of the work. Once one knows what to look for, it’s possible to see and to distinguish them - but it’s hard, since they are almost white.
Most of them are drawn with the “E2” Drawing option (TGraphErrors in a TMultiGraph).
I had the idea that it might help to put a frame around the E2 boxes, i.e. a thin black line at the lower/upper/left/right borders of the box.
Is there some drawing option or some other easy way to achieve this? (If it’s not that easy, don’t bother - then I’ll think of something else.)
