with the pst-func.tex from http://perce.de/LaTeX/pst-func/
It is an undocumented feature, because I do not really
know if the macro works in the right way. Parameters are
N and lambda and all the others are the same as for the
distribution macros (see documentation).



\uput[-90](14,0){$k$} \uput[90](0,0.2){$P(X=k)$}
  fillcolor=blue!10,printValue,valuewidth=20]{13}{6} % {N}{lambda}

The Possion distribution:

\[ P_\lambda(X=k)=\frac{\lambda^k}{k!}\,e^{-\lambda} \]
