with pointcolor

[Dima K. <gn...@di...>]

Hi. I just discovered that there's no "pointcolor" property. So this
doesn't work:

  plot x with points pt 6 ps 2 pointcolor "red"

The "right" way to do it is this:

  plot x with points pt 6 ps 2 linecolor "red"

Which is really surprising. And it means that when plotting with
"linespoints" we can't use separate colors for the line and for the
points. I'm not convinced that we do want to make separate line/point
colors possible, but can "pointcolor" at the very least become an alias
for "linecolor"?

Is there some historical reason for this?

Thanks!
