Graphics, vector-based

• dia can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and simple circuits. It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).

• xfig is an interactive drawing tool which runs under the X Windows System. In xfig, figures may be drawn using objects such as circles, boxes, lines, spline curves, text, etc. It is also possible to import images in formats such as GIF, JPEG, EPSF (Postscript), etc. Those objects can be created, deleted, moved or modified. Attributes such as colors or line styles can be selected from various options. For text, various fonts are available.

  You can start xfig on the command line by typing,

  
   		  xfig &        
  
  
  
• xcircuit is flexible enough to be used as a generic program for drawing just about anything, and is competitive with powerful programs such as "xfig". It is especially good for any task requiring repeated use of a standard set of graphical objects, including architectural drawing, printed circuit board layouts, and music typography. XCircuit is a program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and produce circuit net lists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE net lists. Circuit components are saved in and retrieved from libraries which are fully editable.

  You can start xcircuit by typing the command,

  
   		  xcircuit &

• gnuplot is a command-driven interactive function plotting program. It can be used to plot functions and data points in both two- and three-dimensional plots in many different formats, and will accommodate many of the needs of today's scientists for graphic data representation. It features plotting of two-dimensional functions and data points in many different styles (points, lines, error bars). It allows computations in integer, float and complex arithmetic plotting of three-dimensional data points and surfaces in many different. Styles (contour plot, mesh) and support for complex arithmetic can also be added. It has self - defined functions support for a large number of operating systems, graphics file formats and devices. Please look for the extensive on-line help labels for title, axes, data points command line editing and history on most platforms.
