Yes, this is property "pointinterval" (abbreviation "pi")

    plot "foo" with linespoints pt 9 pi 10  # solid triangle every 10th point

If you give a negative number then the symbol gets whitespace around it,
which makes it stand out more

   set pointintervalbox 2.0
   plot "foo" with linespoints pt 9 pi -10  # nicer version (IMHO)
