the following produces plot in y ticks -1, -0.5, 0, 0.5, 1 , scaling plotted elsewhere, how force matplotlib plot tics in-place -1e-9, -0.5-e9... don't have search other parts of plot potential corrections tick values?

import matplotlib.pyplot plot plot.plot([0, 1e-9, 0, -1e-9]) plot.show()

google led me plot.ticklabel_format(useoffset = false) unfortunately doesn't have usescaling parameter.

one way y-axis tick values, format them like, , add them plot y-axis tick labels.

import matplotlib.pyplot plt plt.plot([0, 1e-9, 0, -1e-9])  # pull out values y-axis ticks yticks = plt.gca().get_yticks()  # format new labels new_yticklabels = ['{:0=4.2f}e-9'.format(tick/1e-9) tick in yticks]  # set new labels plt.gca().set_yticklabels(new_yticklabels)  plt.show()

output
