add "set out"

Version 4.6 is very old. 5.2 is up-to-date.

For plotting symbols your terminal must support the enhanced mode. In
early times there are two different pdf terminals in gnuplot. I'am not
sure if the older pdf terminal supports the enhanced mode.

What shows "gnuplot> show term".

With "gnuplot> help term pdf" you can see what your terminal can do.

Please use pdfcairo enhanced.
gnuplot> set term pdfcairo noenhanced

The pdf-file was generated after a "gnuplot> set out" after the plot
command.
