How to change point size and shape and color in gnuplot   plot    points dat  using 1 2 title with dots   I am using above command to plot graph  but it shows very small size points   I tried to use command   set pointsize 20   but still point size is same

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.

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
