O formatador de escala padrão

O exemplo mostra o uso do padrão ScalarFormattercom configurações diferentes.

Exemplo 1: padrão

Exemplo 2: Sem deslocamento numérico

Exemplo 3: Com Mathtext

Exemplo 1

x = np.arange(0, 1, .01)

         horizontalalignment='center',
         verticalalignment='top')

ax2.plot(x * 1e5, x * 1e-4)

ax3.plot(-x * 1e5 - 1e10, -x * 1e-5 - 1e-10)
