gnuplot plots 2d and 3d graphs, from a data file or with a formula. It has an interactive mode with online help, or it can be used non-interactively. gnuplot does function fitting to data sets, and it does output to many terminals, among which are PostScript, X11 display, PNG, and GIF (via the old gd library).

JpGraph is a Object-Oriented Graph creating library for PHP >= 4.3.1 The library is completely written in PHP and ready to be used in any PHP scripts (both CGI/APXS/CLI versions of PHP are supported). The library can be used to create numerous ... [More] types of graphs either on-line or written to a file. JpGraph makes it easy to draw both "quick and dirty" graphs with a minimum of code as well as complex graphs which requires a very fine grained control. The library assigns context sensitive default values for most of the parameters which minimizes the learning curve. The features are there when you need them - not as an obstacle to overcome! JpGraph is released under a dual license. QPL 1.0 (Qt Free Licensee) For non-commercial, open-source or educational use. [Less]

QPlib plot libraryQPlib is an open-source 2D plotting library for C++ applications, in particular those which make use of Qt. QPlib is designed to be very easy to use. It makes use of the Trolltech Qt class library, and so can be used on Linux, Unix ... [More] , Mac OS X, and MS Windows. The philosophy behind QPlib: it should be very easy to use, plots should look "nice", it should be possible to make plots from the command line (including on Linux/Unix with no X11). Current plots available include: line plots, scatter plots, semi-log and log-log plots, error bars, candlesticks, filled curves, bar charts, 1D histograms, 2D histograms, spectrograms, pie charts. Other features: 5 line styles, 16 symbol types, automatic major and minor ticks or user-defined, custom tick labels, major and minor grids, can have a dependent or independent second y-axis, horizontal and vertical lines can be drawn at user-defined positions, horizontal and vertical transparent shaded regions can be drawn at user-defined positions to highlight regions of interest. Plots can be saved in a variety of file formats including PNG, PDF and SVG. Plots are also available as QImages, which enables them to be used within GUI applications. (QPlib however is not designed to provide interactive plotting widgets). Many example codes are included demonstrating how to use all the main features of QPlib. QPlib is still in a very early stage of development. Installation notesInstallation notes can be found here. Example plotsSome example plots can be seen here. These are taken from the included examples. [Less]
