Editing Reduce (computer algebra system) (section)

== Graphics ==
REDUCE supports graphical display via [[gnuplot]], which is an independent portable open-source graphics package that is included in all REDUCE binary distributions. The REDUCE GNUPLOT package supports the display of curves or surfaces defined by formulas and/or data sets via the command <code>plot(</code>...<code>)</code>. This command exposes some, but not all, of the capabilities of gnuplot. The REDUCE TURTLE and LOGOTURTLE packages are built on the REDUCE GNUPLOT package and support [[turtle graphics]] in two dimensions; the LOGOTURTLE package also exposes additional capabilities of gnuplot, such as control of colour and line thickness, filling and text annotations.
