Re: Matplotlib uses tkinter instead of Agg
Tried x = np.arange(100), x = np.linspace(-2,2,1000) with both python2 and
python3 in %python interpreter. I don't have any problem.

Re: Matplotlib uses tkinter instead of Agg
OK, for this problem, it is discussed at
https://stackoverflow.com/questions/15538099/conversion-of-unicode-minus-sign-from-matplotlib-ticklabels
However, I just tried with Jupyter notebook, and its matplotlib can plot
with negative values on the axes correctly, and
matplotlib.rcParams['axes.unicode_minus'] = True.
Can you guys please check if this only happens to a Python3 environment? I
don't think I am the first one hit this problem.

Re: Matplotlib uses tkinter instead of Agg
Hi,
I worked it out...So I have start a new instance of Zeppelin...creating a
new notebook wont take effect...So all the Python code are executed in one
python vm? Shouldn't separating ones are better?
After I get matplotlib work, I have a new problem.
This code snippet works
%python
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(100)
plt.figure()
plt.plot(x, x**2)
z.show(plt, width='300px')
plt.close()
But if I change x value to x= np.linspace(-2, 2, 1000), as it it used in
the example, I got
[]
Traceback (most recent call last):
File "", line 1, in
File "", line 23, in show
File "", line 69, in show_matplotlib
UnicodeEncodeError: 'ascii' codec can't encode character '\u2212' in
position 17262: ordinal not in range(128)
I did some testing, and I found if any of the value passed to plot()
contains negative numbers, I will get this error...very odd.

Re: Matplotlib uses tkinter instead of Agg
And
matplotlib.use('Agg')
Would only work before matplotlib is first used so you would need to restart
the interpreter. From error stack below it looks like something might be
setting the default backend in matplotlib to TkAgg though.
Are you using the Python interpreter or PySpark interpreter? Also how you are
calling matplotlib like Moon asks?

Hi,
Thanks for sharing the problem.
Could you share which version of Zeppelin are you using and how did you try
matplotlib inside of Zeppelin? Are you trying matplotlib with z.show() ?
Thanks,
