I agree that without points graphs look nicer.
Certainly.
But points may give valuable information, in particular heavy
concentration of points indicates numerical instability (bad
conditioning). And of course points tell you which values were
computed and which are merely interpolation.
I do not question that. My point is
(a) dots seem to be slightly "visually out-of-place" (i.e. not
really on the curve). Or they are drawn too fat.
(b) The default should be "points=off". The user can turn points on
using the 2D control panel.
Unfortunately, I cannot simply give another option to draw, to turn of
points. I only know to kill them after creating the viewport. Any idea
how to achieve the graph directly without points by just *one* command.
