[SciPy-user] 3d plotting question

I might have posted this little bit of code before, but it's not too  
much so I hope no one minds seeing it again. It's not mine, so for  
proper cretids, Google a unique-looking line and it should pop right  
up. With this, you can get to gnuplot with a minimum of fuss. Note  
that it sets up AquaTerm (that's a "plotting terminal" for OS X that  
uses native antialiased graphics with PDF saving, etc. If you don't  
use it, delete the line or set to your own terminal.


import os
class gnuplot:
     def __init__(self):
         print "opening new gnuplot session..."
         self.session = os.popen("gnuplot","w")
     def __del__(self):
         print "closing gnuplot session..."
         self.session.close()
     def send(self, cmd):
         self.session.write(cmd+'\n')
         self.session.flush()
if __name__=="__main__":
     g1 = gnuplot()
     g1.send("set terminal aqua 0")

     # Your code here
     g1.send("plot sin(x)")

     del g1
