the shift by option in fit.powerlaw.plot_ccdf(shift_by='original_data') not working.

[Rahul Kumar]

Hello Jeff,

I am facing the same issue as the previous user but in past, you solved the problem by implementing shift_by='original_data'. But in my case it gives an error

my code is this 

ax = fit.plot_ccdf(original_data=True)
fit.power_law.plot_ccdf(ax=ax, shift_by='original_data')#add powerlaw line

after running it it gives this error

'Line2D' object has no property 'shift_by'

The plot looks like this:

But in actual both empirical data and power-law line fit should superimpose each other
