Re: [Matplotlib-users] plt scale x-axis by constant factor f

[Benjamin R. <ben...@ou...>]

Or just do this:

formatter = FuncFormatter(lambda x, pos: "%d" % x/10)
fig, ax = plt.subplots()ax.yaxis.set_major_formatter(formatter)plt.plot(D.dtrajs[0])
plt.ylabel('O2-Fe distance')
plt.xlabel('Frame')
plt.show()
