Hi:
I want to use the matplotlib style to pyplot, like:

import numpy as np
import matplotlib.pyplot as plt
import proplot as plot

state = np.random.RandomState(51423)
data = 2*(state.rand(100, 5) - 0.5).cumsum(axis=0)

# Simple plot
with plt.style.context('ggplot'):
    f, axs = plot.subplots(ncols=1, figsize=(10, 8))
    axs[0].plot(data, lw=2)
    axs[0].format(xticks=20, xtickminor=False)
    axs.format(
        suptitle='Simple subplot grid', title='Title',
        xlabel='x axis', ylabel='y axis'
    )

But I get the error:

---

TypeError Traceback (most recent call last)
in

5 with plt.style.context('ggplot'):
----> 6 f, axs = plot.subplots(ncols=1, figsize=(10, 8))
7 axs[0].plot(data, lw=2)
8 axs[0].format(xticks=20, xtickminor=False)

578 elif key == 'right':
579 space = units(_notNone(pad, rc['subplots.pad']))

So, why? Thanks very much!
