Hi. Neither of these are working for me. I'm doing this:

  set terminal pdfcairo noenhanced solid color font ",12" size 11in,8.5in
  set output "/tmp/tst.pdf"
  set grid
  set boxwidth 1
  histbin(x) = 1 * floor(0.5 + x/1)
  set pointsize .13
  set linetype 7 lc rgb "#e51e10" pt "#"
  plot '-'   notitle with points pt 7 ps 2
  1 1
  2 2
  3 3
  4 4
  5 5
  e
  set output

I tried these terminals: pdfcairo, png, postscript, x11. None of these
appear to respond to either 'set pointsize' or 'set linetype'. And
setting the pointsize in the 'set terminal' command looks like it's
generally not supported.

Suggestions? 'set pointsize' sounds like it's what I want.

Thanks.
