slope's Issues

Python 3.4 incompatibility

Line 264 breaks on import to python 3.4

Needs to be:

print('fail')

I stumbled upon your great IPython Notebook for the Slope module, but by trying it myself I have issues with the plotting of the labels. The line is continuous where in your results they aren't and show a white background. See this example:

Is there any quick hack to solve this? I tried it on a windows and Linux version resulting in both the same issue.

Thanks!

Error in the Random Data Example

Hello,

I'm not sure if Slope could work with Python 3.5, but I just tried the Random Data Example and the plotting is not as expected.

Code:

import pandas as pd
import numpy as np
from slope.plotSlope import slope
df = pd.DataFrame( np.random.normal(loc=np.ones(shape=[20,30])*np.arange(30)))
df.rename(columns = lambda el : str(el),index =lambda el : str(el),inplace=True)
f = slope(df.T,width =10,height= 8,kind='ordinal',savename='t.png',dpi=200,color={'10':'red','27':'blue'},marker=None)

This code will produce this graph:

These warnings are shown, but from what I understood they are not related to the plotting:
