contour_plot() digunakan untuk memplot dengan dua variabel input. Kita perlu membuat daftar dua variabel di sebelah kanan +tanda, dan perlu memberikan rentang untuk masing-masing variabel. Sebagai contoh:

contour_plot(
  sin(3*pi*t/15)*exp(-.4*x) ~ t & x, 
  domain(t = range(0,40), x = range(0,20)))

Membuat plot perspektif 3 dimensi dengan menggunakan interactive_plot()fungsi contohnya yaitu:

interactive_plot(
   sin(3*pi*t/15)*exp(-.4*x) ~ t & x, 
   domain(t = 0:40, x = 0:20))

contour_plot(
  sqrt( (v-4)^2 + 2*(w-6)^2 ) ~ v & w, 
  domain(v=0:10, w=0:10))

Diatas adalah contoh kontur yaitu {Garis Paralel, Lingkaran Konsentris, Elips Konsentris, Berbentuk X}

contour_plot(
  4*v - 6*w + 4 ~ v & w, 
  domain(v=0:8, w=0:8))

Diatas adalah contoh kontur yaitu:{Garis Paralel , Lingkaran Konsentris, Elips Konsentris, Berbentuk X}}
