[apluslist] Surface plots in A+

[Alexander Skomorokhov]

Hi Pedro,

Better late than never. I missed this message somehow...
I suggest using gnuplot for 3D (and maybe other) plotting. Prepare small
file of
gnuplot commands like the following:
---------------------------------------------
sasha at suse82:~> cat gp
#!/bin/bash
(echo 'set terminal postscript'
echo 'set output "fig.ps"'
echo 'plot "tmp.dat"')>temp.gp
gnuplot temp.gp
\rm temp.gp
---------------------------------------------
I was lazy to prepare data for 3D and use command "plot" here. You have to
use
gnuplot command "splot" for 3D plotting. In the file above you may also set
your
axis labels and stuff like that.

Make it executable:
---------------------------------------------
sasha at suse82:~> chmod +x gp
---------------------------------------------

Now in A+, for example,
---------------------------------------------
     $mode ascii
     rho m       //variable to plot
 100 2
     $>m tmp.dat //write it to tmp file
     sys.system{"./gp"} //plot it with gnuplot
 0
---------------------------------------------

Back to shell. File with postscript of your figure:
---------------------------------------------
sasha at suse82:~> ls fig.ps
fig.ps
View it:
sasha at suse82:~>gv fig.ps
---------------------------------------------
Hope this helps.

Regards,
Sasha.
