Sometimes it may be useful to save every single (x|y) data record of an external file as a node
to draw lines or something else from point to point. The following example first saves all
points (plotpoints=20) of a circle in an external file data.ps. This is done by
PostScript(!), this is the reason why you have to run the PS-output once with ghostscript to
build this file. In a second run the document reads the data file, saves all data records as
nodes N<#>, plots it with the fileplot
macro. After that all nodes are just for fun connected by a line with each other.The files needs the package pstricks-add for the modulo function to draw all this lines:
\multido{\iA=1+1}{\plotpoints}{\psdot(N\iA)%
\multido{\iB=\iA+1}{\plotpoints}{%
\modulo{\iB}{\plotpoints}\nextPoint%
\psline[linewidth=0.1pt,linecolor=blue]%
(N\iA)(N\nextPoint)%
}%

The inverse function of tan(x), the atan(x), has the syntax
y=atan(nominator/demoninator) and the values are in the range of 0..360°.
This is in difference to the default definition of -90...+90°. The following example
shows a plot which uses this last definition (needs pstricks-add).
For the plot of a tan(x) go here
It is also possibe to get the same result with the \parametricplot macro, which
is shown in the above source file and pdf.

The file enclosed below plots the Maxwell-Boltzmann velocity probability
distribution for a sample of gas at 300 K and molar mass 40 g/mol.

| Plotting math functions with pst-plot is given by the range xMin<x>xMax. When there are y values out of the by pspicture defined area, then it is easier to clip the plotting area instead of guessing the minimal and maximal useful x value. The example shows different possibilities to clip the plotting area. | ||

There is also a macro \psFixpoint in the package pst-plot which allows
easier solution than these two ones which work with \multuido.
