[资源] Gnuplot,下了觉得好,顶兄弟一把

http://www.gnuplot.info/


Gnuplot  is a portable command-line driven interactive data and function plotting utility for UNIX, IBM OS/2, MS Windows, DOS, Macintosh, VMS, Atari and many other platforms. The software is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive uses, including web scripting and integration as a plotting engine for third-party applications like Octave. Gnuplot has been supported and under development since 1986.

Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Demos here.

Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey functionality), direct output to pen plotters or modern printers (including postscript and many color devices), and output to many types of file (eps, fig, jpeg, LaTeX, metafont, pbm, pdf, png, postscript, svg, ...) Gnuplot is easily extensible to include new devices. Recent additions include interactive terminals based on aquaterm (OSX) and wxWidgets (multiple platforms).

★★★★★ 五星级,优秀推荐

确实很好用,在命令行下gnuplot运行进入控制台:
>plot "filename" using 1:2 w l lw 2
就可以了。
using 1:2 表示对前两列作图,多列数据可以随意指定其中两列。
w l 是 with line 的简写,意思是用线画图,还可以选点之类的。
lw 2 是线宽。
