The example shows use of the default ScalarFormatter with different settings.

Example 1 : Default

Example 2 : With no Numerical Offset

Example 3 : With Mathtext

import matplotlib.pyplot as pltimport numpy as np

Example 1

x = np.arange(0, 1, .01)fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(2, 2, figsize=(6, 6))fig.text(0.5, 0.975, 'Default settings',
         horizontalalignment='center',
         verticalalignment='top')ax1.plot(x * 1e5 + 1e10, x * 1e-10 + 1e-5)ax2.plot(x * 1e5, x * 1e-4)ax3.plot(-x * 1e5 - 1e10, -x * 1e-5 - 1e-10)ax4.plot(-x * 1e5, -x * 1e-4)fig.subplots_adjust(wspace=0.7, hspace=0.6)

Example 2

x = np.arange(0, 1, .01)fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(2, 2, figsize=(6, 6))fig.text(0.5, 0.975, 'No numerical offset',
         horizontalalignment='center',
         verticalalignment='top')ax1.plot(x * 1e5 + 1e10, x * 1e-10 + 1e-5)ax1.ticklabel_format(useOffset=False)ax2.plot(x * 1e5, x * 1e-4)ax2.ticklabel_format(useOffset=False)ax3.plot(-x * 1e5 - 1e10, -x * 1e-5 - 1e-10)ax3.ticklabel_format(useOffset=False)ax4.plot(-x * 1e5, -x * 1e-4)ax4.ticklabel_format(useOffset=False)fig.subplots_adjust(wspace=0.7, hspace=0.6)

Example 3

x = np.arange(0, 1, .01)fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(2, 2, figsize=(6, 6))fig.text(0.5, 0.975, 'With mathtext',

         verticalalignment='top')ax1.plot(x * 1e5 + 1e10, x * 1e-10 + 1e-5)ax1.ticklabel_format(useMathText=True)ax2.plot(x * 1e5, x * 1e-4)ax2.ticklabel_format(useMathText=True)ax3.plot(-x * 1e5 - 1e10, -x * 1e-5 - 1e-10)ax3.ticklabel_format(useMathText=True)ax4.plot(-x * 1e5, -x * 1e-4)ax4.ticklabel_format(useMathText=True)fig.subplots_adjust(wspace=0.7, hspace=0.6)plt.show()
