PLplot is a cross-platform library of functions that are useful for making scientific plots with UTF-8 symbols and text. PLplot can be used from within compiled languages such as Ada, C, C++, D, Fortran, Java, and OCaml, and interactively from interpreted languages such as Lua, Octave, Perl, Python
... [More], and Tcl.
The PLplot library can be used to create standard x-y plots, semilog plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar charts and pie charts. Multiple graphs (of the same or different sizes) may be placed on a single page with multiple lines in each graph.
A variety of file device formats such as JPEG, PDF, PNG, SVG, and others, as well as interactive device platforms such GTK+, Qt, Tk, and X are supported. [Less]
"Flot is a pure Javascript plotting library". GFlot is GWT adaptation of Flot which combines the high quality charting capabilities of Flot with the power of GWT. In addition, GFlots provides an MVC abstraction layer that ease the development of complex charts and integrates nicely with the GWT RPC infrastructure.
GRAL is a Java library for creating high quality plots and charts. Many plot types are available like scatter plots, bubble plots, line plots, time series, area plots, pie charts, and bar charts. Nearly every aspect of a plot's appearance can be adjusted using a settings system.
Additionally, GRAL
... [More] can interchange and process data in various ways: filters can be used to smooth, derive, or rescale data. Several plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
