GNUPlot—Plotting is fun

Filed under

While strings and pages of data seem cryptic, a plot reveals the entire data flow at a glance. Interpretation suddenly seems much easier. Understanding that maze of numbers is just a glance away. Scientists, mathematicians, engineers, statisticians etc. rely heavily on plots. While OriginLab, an expensive commercial plotting software, is heavily used among university researchers or those blessed with bulging purses, GNUPlot doesn’t lag behind, and is much used by scientists at the IITs, IIScs and universities. In fact, knowledge and skill in GNUPlot is one of the requirements for some of the posts for Senior Research Fellow at the IITs!

The fact that GNUPlot can be used along with applications like Octave makes it even more indispensable.

GNUPlot is a portable command-line driven graphing utility for Linux, MS Windows, OSX, and many other platforms. While the source code is copyrighted, it can be freely distributed. GNUPlot supports many types of plots in 2D and 3D, and can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text, besides Web scripting.
