Re: [ferret_users] pattern pyferret workaround

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Patrick,
The plot marks available for PLOT/SYMBOL= are quite thoroughly 
harde-coded into Ferret/GKS.  For now I think the only way to do that 
would be to use a large number of LABEL commands to put other symbols on 
a plot.  I have not experimented with that to see how well it works. Of 
course it's not that convenient but a script might be written to do it 
in a general way.

We are just getting underway a project to call true fonts from 
PyFerret.  When it is done, this should make it possible to work with 
symbols from various font families.
