Notes Engineering Symbols in Gnuplot
Read more...
I've had a hard time in the past finding the symbols I want from gnuplot. Typically I am using the "postscript eps" terminal with Helvectica font. So I decided to write a matlab script to use gnuplot to generate all the possible symbols for this font in this terminal. That way, I can have a PDF that I can refer to when I need to find the symbol number.
Recall that a symbol is printed in gnuplot (using enhanced mode) via the syntax {/Symbol \245} where the number represents the symbol you want. I had a hard time figuring out which symbol number to use and found many conflicting numbers online.
Enter my Matlab script. It loops over symbol numbers from 1 to 1200 (way higher than needed) and generates them into pdf files using gnuplot, then assembles the pdf files using ghostscript.
The result is the attached PDF of the symbol map of Helvetica font as generated from gnuplot using the pdf terminal. It's a little rough, but at least I can browse for symbols. The empty symbols that look like garbage are not real and probably could be avoided if I had counted in octal numbers or something.
I have also attached the matlab script.

I am not able to find the perpendicular symbol. Although I have tried with the {/symbol\136} with
set terminal postscript eps enhanced "Helvetica" 20
but it is not working in my case.
Please help me in this regard.
You need to capitalize the word Symbol and put a space in your syntax, like {/Symbol \136}. The following syntax works for me to produce a perpendicular symbol:
set zlabel '{/Symbol \136}'
If I do not capitalize Symbol or put a space between Symbol and \136, it won't work.
Kind Regards,
Judson
