A template using PHP, python, Fortran, gnuplot. UNDER CONSTRUCTION

Chi-square 'df' Chi-square degrees of freedom (from, to) for 3D plot.
x range Range of x for plot.
Points Number of points for graph.
Show values Show graph coordinates.

This is essentially a template to show the combination of PHP, python, Fortran 90, and gnuplot.

The files involved are: (a) P-perspyfog.php (this one), in a general subject directory ('qc', "quality control");  and, in a particular subdirectory ('chisquare'), (b) perspyfog.php, 'action' manager; (c) Perspyfog.py, python hub calling following and 'gnuplot'; (d) module from modForm.f90.

Advantage is taken from: PHP, for the web page construction; python, as "glue"; Fortran, for easy numerical file handling; and gnuplot, for (2D & 3D) plotting. Anomaly: the results of Linux 'wc' appear out of order.

Draws a 2D and a 3D graphs of various chi-square density functions.
