The STIMATH library allows you to plot a given expression against a set of values on a rectangular, or a polar, or a hyperbolic axis.
The library also allows you to zoom in, scale up or create a transparent plot. All the functionalities can be easily obtained through a set of user-friendly command line arguments.
STIMATH can also be used in data analysis, by displaying any data file as a graph, or by generating a corresponding chart.

Created: December 2007

Features:

Executes mathematical expressions or formulas directly, from the command line

The command line that can be used to generate all plots on the three existing cartesian, polar and hyperbolic axis

Plots can be colored or have their colors modified

Plots can be zoomed, scaled, offset, cropped, x-axis and y-axis or

Labels can be added to plots

Usage:
To generate and plot a function on the X axis, type:

stimath [expression]

For example:

stimath sin(2*t)*exp(cos(3*t))

This will generate a plot in which the Y-axis is the x-axis, and the
X-axis is the Y-axis:

stimath sin(2*t)*exp(cos(3*t))

min: -180 max: 180
step: 0.1
max: 0.1
display: false

where:
min/max: minimum/maximum values of the plot;
step: increment of the X axis;
display: if the values of the expression are plotted on a logarithmic scale, if so how many points are used to generate the curve.

For example:

stimath 1/(x+1)^2+2

This will generate a plot in which the X-axis is the Y-axis, and the
Y-axis is the X-axis:

stimath 1/(x+1)^2+2
