The pointsize command scales the size of the points used in plots.
Syntax:
set pointsize <multiplier>
show pointsize
The default is a multiplier of 1.0. Larger pointsizes may be useful to make points more visible in bitmapped graphics.
The pointsize of a single plot may be changed on the `plot` command. See with for details.
Please note that the pointsize setting is not supported by all terminal types.
