Computes Poisson
probabilities and their Gaussian approximation,
(μ, σ) = (λ,
√λ). This is essentially a template
for multi-column, histogram-type plots in gnuplot.
Draws a graph of the probabilities for the
Poisson probabilities and their Gaussian approximation.
Computation structure — A PHP file
(this page: 'P-histogram.php') calls
(via 'action=') an intermediate PHP file ('Histogram.php'),
which (through $_POST) sends the problem data as command line arguments
to a Python script. This last does the computing, and executes
graphing via 'gnuplot' (system call), for the final (temporary) webpage.
Keywords: PHP, command line arguments,
Python script, gnuplot, template.
