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

[Christian J. <chr...@gm...>]

Sterling,

this doesn't work, as it's using the array as a function

x = D.dtrajs[0](range(len(D.dtrajs[0])))

plt.plot(D.dtrajs[0])

plt.ylabel('O2-Fe distance')

plt.xlabel('Frame')



---------------------------------------------------------------------------TypeError
                                Traceback (most recent call
last)<ipython-input-147-8bbee6b254c1> in <module>()----> 1 x =
D.dtrajs[0](range(len(D.dtrajs[0])))      2 plt.plot(D.dtrajs[0])
3 plt.ylabel('O2-Fe distance')      4 plt.xlabel('Frame')
TypeError: 'numpy.ndarray' object is not callable
