matplotlib-colorbar's Issues

UserWarning: This call to matplotlib.use() has no effect

When importing from matplotlib_colorbar.colorbar import Colorbar after matplotlib has already been imported, say with %matplotlib inline, a warning comes up:

/Users/username/anaconda3/envs/scipy/lib/python3.6/site-packages/ipykernel/__main__.py:8: UserWarning: 
This call to matplotlib.use() has no effect because the backend has already
been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.

I managed to trace the warning, and it's coming from matplotlib_colorbar/colorbar.py, line 83:

imp.reload(sys.modules['matplotlib'])

If this is OK, maybe you can suppress the warning?

import warnings
with warnings.catch_warnings():
    warnings.simplefilter("ignore", UserWarning)
    imp.reload(sys.modules['matplotlib'])

Colorbar size depends on data scale

The scale of the drawn colorbar is not independent of the data scale.

The following code generates the following image

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cbook as cbook
from matplotlib_colorbar.colorbar import Colorbar
%matplotlib inline
data = np.array(plt.imread(cbook.get_sample_data('grace_hopper.png')))
mappable = plt.imshow(data[...,0],  cmap='viridis')
colorbar = Colorbar(mappable, location='lower left')
plt.gca().add_artist(colorbar)

image

Modifying the data scale (by multiplying by 15) with the following code generates this image

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cbook as cbook
from matplotlib_colorbar.colorbar import Colorbar
%matplotlib inline
data = np.array(plt.imread(cbook.get_sample_data('grace_hopper.png')))
mappable = plt.imshow(data[...,0]*15,  cmap='viridis')
colorbar = Colorbar(mappable, location='lower left')
plt.gca().add_artist(colorbar)

image

Colorbar is ignoring the norm

It seems that the colorbar is not providing norm to the PatchCollection, resulting in the wrong colors being plotted.
