If any of you use spice3, you no doubt have had noticed the low, low quality
of hardcopy plots (I am talking about the ones resulting from running under
Xwindows, not the chararacter plots).
Well I did, and so I sat down and wrote a filter to make spice3 'print'
statement outputs suitable for input to xgraph. Which in turn makes really
nice graphs which you can also include in latex documents if you want.
Some of you might want to use it, so here it is:
(how to get xgraph is described in the shar file also)
#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create the files:
# readme
# sp2xgraph
# sp2xgraph.shar
# This archive created: Thu Oct 11 22:03:46 1990
export PATH; PATH=/bin:$PATH
if test -f 'readme'
then
echo shar: will not over-write existing file "'readme'"
else
cat << \SHAR_EOF > 'readme'
This shell script is a filter to help make presentation quality graphs from
spice3 output, it filters output from spice3 'print' statements to a form
suitable for input to xgraph.
xgraph is a program to plot data sets on an Xwindows display, it is available
by anonymous ftp from shambhala.berkeley.edu (128.32.132.54). These graphs can
then be output in several formats including HPGL, and encapsulated postscript.
Resulting output is much better than what you can get from hardcopies
of plots in spice3, and to boot it can be included as encapsulated postscript
in latex documents (don't ask me how to do this, I haven't tried yet).
