Python Graphing Attribute Error

I edited the code with the suggestions and currently receive this error Traceback (most recent call last): File "C:\Users\Jonathan.HollowayMainPc\Documents\Inchimoku Kinko Hyo.py", line 111, in ichimoku_chart() File "C:\Users\Jonathan.HollowayMainPc\Documents\Inchimoku Kinko Hyo.py", line 97, in ichimoku_chart facecolor='green', alpha=0.2, interpolate=True) File "C:\Python27\lib\site-packages\matplotlib\pyplot.py", line 2826, in fill_between interpolate=interpolate, **kwargs) File "C:\Python27\lib\site-packages\matplotlib\axes_axes.py", line 4345, in fill_between raise ValueError("Argument dimensions are incompatible") ValueError: Argument dimensions are incompatible

My code is below not sure what is causing it. Any help would be appreciated.
