How to show π symbol on x axis?

Question

Feel frustrated when I cannot add a simple \"π\" symbol on x axis. I searched lots of solution and there is what I use:

set terminal postscript eps enhanced
set          


        

Answer 1

I experience the same problem and found a workaround. If I open the resulting eps file from gnuplot in Inkscape and save it as eps file again, the pi character renders as it should. I just use the basic import, not the Poppler, but it's worthy experimenting with both. If I then open the new eps file with Preview, the pi characters are there.
