Summary0011971: 2D Charts Sometimes Pick Ugly Colors
DescriptionAlthough a lot of thought went into choosing the colors for 2D charts, the way colors are selected sometimes undermines the color palette. For an example, do the following:

1. Load can.ex2, load all variables, apply.
2. Plot Over Line. Apply.

The resulting plot (an example is attached) has terrible colors. The colors have poor contrast with each other and with the background. In addition, it just does not look good.

The problem is that colors are assigned to all variables, but only a few are actually drawn (some are suppressed for good reason). The best colors are the first in the list, and most of those are skipped over.

I'm not sure what is the "right" thing to do here. Perhaps all components of a vector could be assigned the same color (or perhaps different shades of the same color). Since most of the hidden series are vector components, that might be a good enough solution.

Not saying this has been resolved for good, but the changes in logic to pick the default colors seems have overcome this issue for this particular use-case (see attached image).

We can revisit as and when needed.

Looks good. I did Ken's test below, then went to last timestep. Colors look OK.

Tested master, remote server, Linux.
