Thanks  a lot,

   I am very new to using the matplotlib.  I am wondering if I can use
just matplotlib without using pylab at all?  I have rough idea that I
can try to find the class that has the function pylab has and use it
instead

  Please let me know what I need to be be aware of?

Thanks,
Deen
