Hola,

estoy tratando de hacer algunas animaciones usando draw, pero no he tenido exito. Listo abajo los códigos y los problemas,

Gracias,

Aniura

Primer intento:(tomado de: http://www.johnlapeyre.com/qinf/qinf_html/maxima_html/maxima_48.html)

(%i1) load(draw)$
(%i2) draw(
        delay     = 100,
        file_name = "zzz",
        terminal  = 'animated_gif,
        gr2d(explicit(x^2,x,-1,1)),
        gr2d(explicit(x^3,x,-1,1)),
        gr2d(explicit(x^4,x,-1,1)));

Segundo intento (tomado de: http://riotorto.users.sourceforge.net/gnuplot/ps/index.html)

set_draw_defaults(
  xrange = [1,2.5],
  yrange = [1,3],
  label_alignment = left )$

greek_word:
  ["{/Symbol P} ",
   "{/Symbol u} ",
   "{/Symbol t} ",
   "{/Symbol a} ",
   "{/Symbol g} ",
   "{/Symbol o} ",
   "{/Symbol r} ",
   "{/Symbol a} ",
   "{/Symbol s} "] $

dynamic_word:
  makelist(
    block([word:""],
      for i:1 thru k do word: concat(word, greek_word[i]),
      gr2d(label([word,1.3,2]))),
    k, 1, length(greek_word)) $

draw(
  delay      = 100,
  file_name  = "greek",
  dimensions = [400, 200],
  terminal   = 'animated_gif,
  dynamic_word  )$
