plot fracdiff and raw at same chart

[rspadim]

at ["Fixed Window Fractional Differencing Function (CPU)"], include the raw data, to easily see the difference between both charts =)
great work, congrats!

Plot

plt.figure(figsize=figsize)
plt.subplot(2,1,1)
plt.plot(df_raw_fd)
plt.subplot(2,1,2)
plt.plot(df_raw)
plt.show()

This would be a nice comparison chart. I'll add it in. Thanks!

• i forgot to sync X axis

sharex=true, at subplot, and probably pass X (index) at plot() function
