Nice tutorial.
But this statement no longer holds:
Beim Gnuplot-Interface Draw ist es nicht m?glich, Defaultwerte f?r die
Optionen zu setzten
since we now (Maxima 5.18) have funcion 'set_draw_defaults':
@deffn {Function} set_draw_defaults (@var{graphic option}, ...,
@var{graphic object}, ...)
Sets user graphics options. This function is useful for plotting a sequence
of graphics with common graphics options. Calling this function without
arguments removes user defaults.
Example:
@example
(%i1) load(draw)$
(%i2) set_draw_defaults(
xrange = [-10,10],
yrange = [-2, 2],
color = blue,
grid = true)$
(%i3) /* plot with user defaults */
draw2d(explicit(((1+x)**2/(1+x*x))-1,x,-10,10))$
(%i4) set_draw_defaults()$
(%i5) /* plot with standard defaults */
draw2d(explicit(((1+x)**2/(1+x*x))-1,x,-10,10))$
@end example
Thanks Wilhelm (and Wolfgang).
