Here is one of our plot symbol routines.
It accepts numbers as well as strings.
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/icgsym_n.tar.gz
For further routines and licensing please have a look at
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_lib_intro.h tml
try:
x=findgen(10)
y=sin(x)
icgsym_n,'circle'
plot,x,y,psym=8
with icgsym_n,/symhelp you get a list of numbers and names
e.g. 218 is a half filled circle
