labels not displaying for ppl.fill_between()

[slink]

Copying and pasting code almost verbatim from here

import prettyplotlib as ppl
import numpy as np
# prettyplotlib imports 
import matplotlib.pyplot as plt
from prettyplotlib import mpl
from prettyplotlib import brewer2mpl

# Set the random seed for consistency
np.random.seed(12)

fig, ax = plt.subplots(1)

# Show the whole color range
for i in range(8):
    y1 = np.random.normal(size=1000).cumsum()
    y2 = np.random.normal(size=1000).cumsum()
    x = np.arange(1000)

    ppl.fill_between(x, y1, y2, label=str(i))

ppl.legend()

I get the error:

/Users/xxxx/anaconda/lib/python2.7/site-packages/matplotlib/axes/_axes.py:475: UserWarning: No labelled objects found. Use label='...' kwarg on individual plots.
warnings.warn("No labelled objects found. "

I'm using anaconda 1.9.0, with numpy 1.8.2, and matplotlib 1.4.0. Any thoughts regarding how to get labels to show up with ppl.fill_between() would be greatly appreciated.

I have the same issue... When i tried to reproduce the plot with the same code. I get a very clumsy colors as follows. I have no idea how to fix it. I tried it in my anaconda distribution as mentioned above and also installed all the dependencies in my system python distribution.

This is because fill_between doesn't act the same as lines.

Thank you for your comment. Unfortunately, I no longer have the bandwidth to maintain prettyplotlib. I recommend using seaborn. Using seaborn, to get the prettyplotlib style, do:

import seaborn as sns
sns.set(style='ticks', palette='Set2')

And to remove "chartjunk", do:

sns.despine()

If you have discrete pull requests, I will accept them, but I personally will no longer fix bugs.
