The points are drawn at an arbitrary size, and you cannot expect
that size to be consistent across terminals.  Furthermore, the
size of the point itself is independent of the current size of the
canvas (I think, anyhow, it is possible that there are some terminal
types for which this is not true).

There are two alternatives which give you more control over the
scaling of the plotting symbols, allowing the size to be on some
absolute scale relative to the plot axes or to the canvas size.

4.2 or 4.3:
Use "with labels" rather than "with points", and control the size
of the symbol by changing the font size.  An extreme example is
here:

4.3 only:
Use "plot ... with circles", which allows you to give the radius of
each circle in either axis coordinates or absolute sizes.
