Hi, I have a bunch of x-y data contained in an array. I would like to plot the data using an external program (psxy in GMT). The plotting program takes x-y couples as standard input. How do I get the data into the system call? I used to do things in csh and awk, i.e., something like
awk '{<some manipulations here>; print $1, $2}' filename | psxy <some options> >! output.ps The reason I'm trying to use python is because the manipulations are getting too cumbersome in awk. Now I have all the manipulations done in python, but I'm missing that last step. I've tried various things with os.system, popen, and subprocess, but so far without success. Does anyone know how to do this? chris ------------------------------------------------------------------------ ------------------------------------------- Christoph Hieronymus [EMAIL PROTECTED] Associate Professor phone: (+46) 18-471 2383 Uppsala University fax: (+46) 18-501 110 Dept. of Earth Sciences (Geophysics) Villavägen 16 SE-752 36 Uppsala, Sweden -- http://mail.python.org/mailman/listinfo/python-list
