Solution 1 - Gnuplot

Use the pointtype and pointsize options, e.g.

plot "./points.dat" using 1:2 pt 7 ps 10

where pt 7 gives you a filled circle and ps 10 is the size.

See: Plotting data.

Solution 2 - Gnuplot

The pointsize command scales the size of points, but does not affect the size of dots.

In other words, plot ... with points ps 2 will generate points of twice the normal size, but for plot ... with dots ps 2 the "ps 2" part is ignored.

You could use circular points (pt 7), which look just like dots.

Solution 3 - Gnuplot

plot "./points.dat" using 1:2 title with dt 2 lw 4
