.SH PLOTTING COMMANDS
220
217
Maxima is capable of producing 2- and 3-dimensional plots. Here is a
221
218
simple 2-dimensional example
223
.B plot2d(sin(x),[x,-2*%pi,2*%pi]);
220
.B plot2d (sin(x), [x, -2*%pi, 2*%pi]);
225
222
and a simple 3-dimensional example
227
.B plot3d(2^(-u^2+v^2),[u,-5,5],[v,-7,7]);
229
By default plotting is done by a TCL/Tk application supplied with
230
Maxima. If gnuplot is available, it can be used by setting a plot
233
.B set_plot_option([PLOT_FORMAT,gnuplot]);
235
For more information, see "? plot".
224
.B plot3d (2^(-u^2 + v^2), [u, -5, 5], [v, -7, 7]);

By default plots are made by the

\fBMAXIMA_PREFIX\fR
279
275
Maxima looks for its input files in the directory configured at
280
276
compile time, \*(Pr. Maxima can be relocated to a different directory
281
as long as the maxima script maintains the same relative position with
282
respect to the Maxima input files. If, for some reason, the maxima
279
script maintains the same relative position with
280
respect to the Maxima input files. If, for some reason, the
283
282
script needs to be relocated independently, \fBMAXIMA_PREFIX\fR needs to be
284
283
set to point to the top of the tree holding the input files.
288
287
included only for backward compatibility with older versions of Maxima.
290
289
Maxima uses several other environment variables for communication
291
between the maxima script and the lisp image. All such variables start
292
script and the lisp image. All such variables start
292
293
with \fIMAXIMA_\fR. They should not need to be modified by the user.
