# Histogram and \lambda parameter of the laplacian curve.

Fri Jul 25 20:50:05 CEST 2008

Thanks everyone for your earlier help.

I have to plot a histogram of values lets say [0.5,0.6,0.8,0.9].I guess the
histogram would show an exponential decay ie, the laplacian curve.

I need to find the \lambda parameter of this curve .

So please tell me if  it be done through
http://matplotlib.sourceforge.net/and are there any other libraries
which can be used.
