Hi all,
from how I understand plotting using openmath works is that xmaxima
makes these plots by itself without calling the omplotdata script.
Most of omplotdata script is probably included in the xmaxima script.
I guess this behaviour is controlled by in_netmath and show_openplot
variables. If you set in_netmath to false and show_openplot to true
plotting does not work in xmaxima.
Other interfaces (wxmaxima, wintexmacs, commandline) would use the
omplotdata script to plot using openmath. This does not work because:
1) tcl/tk is usually not installed by default on windows
2) the script is called omplotdata instead of omplotdata.tcl - the
#!/bin/sh
# comment \
exec wish84 "$0" "$@"
trick does not work on windows
3) omplotdata expects unix cat program to be installed - this is near
the end of omplotdata
if { [lindex $argv 0] == "plotdf" } {
lappend omcommand "plotdf"
} else {
lappend omcommand [exec cat [lindex $argv 0]]
}
I propose that we change omplotdata to omplotdata.tcl and somehow deal
with problem 3). Then if someone complains that plotting using
openmath does not work we can simply say that tcl/tk needs to be
installed. (BTW, I always copy omplotdata to omplotdata.tcl and add
the cat program and plotting using openmath works since I have tcl/tk
installed - there's no need to edit the plot.lisp file).
As for using plotdf from console (or wxmaxima) - this will not work
out of the box even if we have openplot working. I can provide a patch
for plotdf.lisp which fixes this if anyone is interested.
HTH,
Andrej
