The basic workhorse command of PyXPlot is the plot command, which is used to produce all plots. The following simple example would plot the function :
plot sin(x)
It is also possible to plot data from files. The following would plot data from a file ‘datafile’, taking the -coordinate of each point from the first column of the datafile, and the
-coordinate from the second. The datafile is assumed to be in plain text format, with columns separated by whitespace and/or commas†If the filename of a datafile ends with a .gz suffix, it is assuming to be gzipped plaintext, and is decoded accordingly.:
plot 'datafile'
Several items can be plotted on the same graph by separating them by commas:
plot 'datafile', sin(x), cos(x)
It is possible to define one’s own variables and functions, and then plot them:
a = 2 b = 1 c = 1.5 f(x) = a*(x**2) + b*x + c plot f(x)
To unset a variable or function once it has been set, the following syntax should be used:
a = f(x) =
