Summary[edit]
| Description |
English: 3D plot of the function towards the origin with projections of the curve on the xz and yz plan. The lines of the projections are bluest the nearest they are to zero)
Français : Représentation 3D de la fonction vers l'origine, munie de projections sur les plans xz et yz. Les lignes de la projection sont de plus en plus bleues à mesure que ce sont des projections de la courbe proches de zéro. |

fig = plt.figure()
ax = fig.gca(projection='3d')
X = np.arange(-.1, 2, 0.09)
Y = np.arange(-0.1, 2, 0.09)
X, Y = np.meshgrid(X, Y)
Z = (X**2 * Y**2)/(X**4+Y**2)
cset = ax.contour(X, Y, Z, zdir='y', offset=2, cmap=cm.seismic)
