i would like to know if there is some way for customize the point symbols in a plot generated in gnuplot? I want to change the symbols in a plot by numbers, for example, change all '+' symbol by the number '1'.
Every help will be appreciated.

Yes, just use pt '1' as long as you are plotting with points. For example, try:
plot sin(x) with points pt '1'

I forget to say that i'm plotting using the pdfcairo terminal. Respect you answer, I tried but is not working, neither by using 'x11' terminal – Handel Sarache Jul 04 '18 at 15:57

Hmmm. I just tried the x11 terminal and it works there. Are you upgraded to gnuplot 5? – Dan Sp. Jul 04 '18 at 15:59

It's working, so many thanks. Another question, the syntax used in the older versions to change the point's color it's no working when i use the number instead the usual characters. There is another way to change the points color? by the way, thanks by the hint – Handel Sarache Jul 04 '18 at 16:25

You can use `plot sin(x) with points pt '1' textcolor rgb "red"`. Take a look at `help textcolor`. – user8153 Jul 04 '18 at 18:31
