Nabla & Greek letters

[Dirk Geyer]

Hi,

I am trying to put Greek letters and in particular Nabla in a plot,
working with Windows 2000. All my attempts up to now failed, even using
the suggestions from the FAQ's . Does anyone have an solution ?

Thanks,

Dirk

Here is the script file, wher I tried to use gamma :

set origin 0, 0
set output 'D:\raman\diimfi\plot\gradu_hist.ps'
set terminal postscript portrait enhanced 'Helvetica,14'
#set grid

set origin 0.0, 0.0
set size 0.9, 0.45

#' ---------------------------------------------

set xtics 0.0,100,500
set mxtics 5
#set xlabel '{/Symbol g} grad |u| [-]' #'Helvetica,16'
#set xlabel '{\g} grad |u|' 'Helvetica,16'
set xlabel '(\gamma)\ grad |u|' 'Helvetica,16'

set logscale y
set format y "%7.3f" ;
set ytics 0.0001,0.1,1.0
set mytics 10
set ylabel 'PDF [-]' 'Helvetica,16'

set key right spacing 1.5

plot [0:500][0.0001:0.3]\
'E:\ra_meas\mar14\ram\fil3\mc01_0000_hist_gradu_avg.dat' u 2:($5/100.0)
title ' 0 steps' w l 1,\
'E:\ra_meas\mar14\ram\fil3\mc01_0025_hist_gradu_avg.dat' u 2:($5/100.0)
title ' 25 steps' w l 2,\
'E:\ra_meas\mar14\ram\fil3\mc01_0050_hist_gradu_avg.dat' u 2:($5/100.0)
title ' 50 steps' w l 3,\
'E:\ra_meas\mar14\ram\fil3\mc01_0100_hist_gradu_avg.dat' u 2:($5/100.0)
title '100 steps' w l 4,\
'E:\ra_meas\mar14\ram\fil3\mc01_bavg_0000_hist_gradu_avg.dat' u
2:($5/100.0) title 'avg frame' w l 5

reset

Nabla is *not* a Greek letter, it's a mathematical symbol in its own
right.

The syntax you left un-commented is for TeX, not for Postscript
enhanced mode. You'ld need the syntax shown in the first of these
three lines, but a letter other than 'g'. Check out 'help enhanced',
and the enhanced postscript documentation file, "ps_guide.ps".
