gnuplot:让你的数据可视化

Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS,
and many other platforms. The source code is copyrighted but freely distributed (i.e., you don't have to
pay for it). It was originally created to allow scientists and students to visualize mathematical functions
and data interactively, but has grown to support many non-interactive uses such as web scripting. It is
also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and
under active development since 1986.
Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes,
contours, vector elds, surfaces, and various associated text. It also supports various specialized plot
types.

Gnuplot supports many dierent types of output: interactive screen terminals (with mouse and hotkey
input), direct output to pen plotters or modern printers, and output to many le formats (eps, g,
jpeg, LaTeX, metafont, pbm, pdf, png, postscript, svg, ...).
