This is how the code looks like now:
=== BEGIN ===
import matplotlib as mpl
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import sys
import paho.mqtt.client as mqtt
import itertools
def update_line(num, dataLines, lines):
 for line, data in zip(itertools.repeat(lines, len(dataLines)), dataLines):
 line.set_data(data[0:2, :num]) #
IndexError too many indices
 line.set_3d_properties(data[2, :num])
 return lines
def on_connect(client, userdata, flags, rc):
 print("Connected with result code "+str(rc))
 client.subscribe("hello/world")
def on_message(client, userdata, msg):
 global x, y, z
 data = msg.payload
 print(msg.topic+" "+str(msg.payload))
 point = np.asarray([float(element) for element in data.split()])
 print point
 x=np.concatenate((x,[point[0]]))
 y=np.concatenate((y,[point[1]]))
 z=np.concatenate((z,[point[2]]))
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
x = np.array([1.0, 2.0, 3.0])
y = np.array([4.0, 7.0, 8.0])
z = np.array([6.0, 9.0, 5.0])
data = [x, y, z]
lines, = ax.plot(x, y, z, label='Line')
ax.legend()
client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.connect_async("localhost", 1883, 60)
client.loop_start()
line_ani = animation.FuncAnimation(fig, update_line, 25, fargs=(data,
lines), interval=2000, blit=True)
plt.show()
=== END ===
So, the error now is in line.set_data where it says there are too many
indices. If I remove :num, in both line.set_data and
line.set_3d_properties, it tells me that 'TypeError': 'Line3D' is not
iterable.
Thanks for patiently answering my queries.

Sorry for bother, not sure if this goes through or not.
I had a plot with hatch in it. But the default linewidth for hatch makes it
really hard to see in my current figure layout/scale, so I would like to
increases the hatch linewidth;
plt.bar(ind, s1[:,3],width, color='0.85', edgecolor='black',
linewidth=[0.5],hatch='-----//////')
The linewidth there can only change the width of the edge, but not the
hatch width;
I did several google searches with no solution. But I indeed noticed that
several years ago (back to year 2011), this is impossible as the hatch
linewidth is hard coded as:
hatch_path_stroke.width(1.0);
But is this implemented so that I can change the hatch linewidth?
Best regards
Luis

You have some logic issues here. First off, I wouldn't be updating the plot
in the same function that is updating the data values. Assuming that
"loop_start()" is asynchronous, the update frequency for it is likely to be
entirely different from the Animation update frequency. So, just have that
function do updates. You should also declare x, y, and z as globals in that
function so that the reassignment of those arrays persist properly.
Your list comprehension prior to concatenating uses a variable "x", which
is likely causing the current error that you see. Change that name to
something else.
Lastly, I implore you to use "set_data()" like in the original example,
rather than calling plot() repeatedly.
Cheers!

Hi,
I was able to get past the error, and I am now trying to add a

Line3D.set_3d_properties is not doing anything to turn zs into an 
ndarray; in fact, when zs is a scalar, it is turning it into a list. I 
suspect this is the place to make it an array. Probably better here 
than anywhere farther down. It also looks to me like Line3D.__init__ 
should be using self.set_3d_properties.

Dear Pythonistas,
We have just released a new version of the "scipy lecture notes":
http://www.scipy-lectures.org/
These are a consistent set of materials to learn the core aspects of the
scientific Python ecosystem, from beginner to expert. They are written
and maintained by a set of volunteers and published under a CC-BY
license.
Highlights of the latest version includes:
 * a chapter giving a introduction to statistics in Python
 * a new layout with emphasis on readability including on small devices
 * fully doctesting for Python 2 and 3 compatibility
We hope that you will find these notes useful, for you, your colleagues,
or your students.

And this is a bug in matplotlib that needs to be fixed. Your solution is
just a workaround to an existing problem in matplotlib.

I did not ask you to investigate anything for me. You made the assertion
that the user was multiplying a list by a float, therefore, I assumed that
you were seeing something that I had not seen.

I realize that, and that isn't in dispute. Nowhere did I say that
converting the lists into numpy arrays would not solve the problem.

Of course the second operation isn't visible. I did say that it happens
"under the hood". His program is perfectly valid (albeit not ideal) and
demonstrated a bug in matplotlib's codebase. That is why I asked him to
file a bug report. My reading of your email is that you are upset for some
reason, but I have no clue why.

Look, Benjamin Root, I don't know, and I will not "investigate" where 
this operation happens. The diagnosis is a standard Python message. 
Thus, I took the program of Shakhti Kannan, and in a few seconds I changed
x = [1.0, 2.0, 3.0] into x = np.array([1.0, 2.0, 3.0])
and in update_line: x.append(1.0) into x=np.concatenate((x,[1.0]))
And the program began to run without error messages. So, please, these 
are FACTS: somewhere the lists x,y,z get down in this draw stack.

There are two different issues, accepting any sequences/iterators is 
one, converting them into arrays - another one. This second operation 
visibly doesn't take place.

That shouldn't matter. ax.plot() accepts lists as valid inputs and it
should be converting them into numpy arrays under the hood. Indeed, if one
takes out the animation creation, the code works just fine. Adding new
plots(), while inefficient, shouldn't cause this problem.
Ben Root

Shakhti Kannan tries to multiply a list by a float, and Python disagrees.
Le 28/09/2015 17:43, Benjamin Root comments :

I suspect that it can be solved without Hercule Poirot.
Convert *at the beginning* your lists x,y,z into np.arrays.
(also: append ==> concatenate)

Confirmed using a fairly recent matplotlib checkout. Could you file a bug
report? This is going to need some investigating.
As a side note though, the way you are updating the lines by calling
`ax.plot` repeatedly, is bad form. You want to update the lines object
itself, by calling its "set_data()" method. Also, move the call to
`ax.legend()` to after calling `ax.plot` to avoid the warnings about
unlabeled plotting objects.

Hi,
I am trying to create poly lines using matplotlib and animation. My
code snippet is as follows:
=== BEGIN ===
import matplotlib as mpl
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
def update_line(num, x, y, z, l):
 x.append(1.0)
 y.append (2.0)
 z.append(3.0)
 print x, y, z
 l, = ax.plot(x, y, z, label='Line')
 return l,
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
ax.legend()
x = [1.0, 2.0, 3.0]
y = [4.0, 7.0, 8.0]
z = [6.0, 9.0, 5.0]
l, = ax.plot(x, y, z, label='Line')
line_ani = animation.FuncAnimation(fig, update_line, 25, fargs=(x, y,
z, l), interval=2000, blit=True)
plt.show()
=== END ===
The error that I get:
=== ERROR ===
$ python mat-3.py

labeled objects found. Use label='...' kwarg on individual plots.

I am using the basic_example.py as a template.
http://matplotlib.org/1.4.1/examples/animation/basic_example.html
What could I be missing? Appreciate any help in this regard,
Thanks!

I have not used `easy_install` recently. I would suggest trying pip, or
doing a source install from a git checkout.
I also have not seen that error message at the bottom before.

Thank you Christoph, and thank you for the extensive package builds!
I did update to matplotlib 1.5 and it seems to address the error; I get all
of my plots and they look correct, though I did get the following warning
on Python 2.7.10:
[c:\python\dev\homework1] python PHYS404-homework1-problem3-rev05.py
C:\Python27\lib\site-packages\numpy\core\fromnumeric.py:2648:
RuntimeWarning: invalid value encountered in rint
 return round(decimals, out)
... and the same on CPython 3.4 (do you think 3.5 is stable enough to move
to?):
[c:\python\dev\homework1] python PHYS404-homework1-problem3-rev05.py
C:\Python34\lib\site-packages\numpy\core\fromnumeric.py:2648:
RuntimeWarning: invalid value encountered in rint
 return round(decimals, out)
Many thanks again,
Bobby

One more note: changing the plot type from loglog to just plot, the errors
also go away.

I can reproduce the AttributeError on all Python versions and the crash 
(in Python's _tkinter.pyd extension) on Python 3.4.
As a workaround you might try to upgrade to matplotlib 1.5, which seems 
to work for me.

Hi,
I am trying to install matplotlib on my RedHat Linux 6.5 with Python33.
Unfortunately, 'matplotlib' rpm isn't available for python33. `python-matplotlib` is included only for python2.6 from Red Hat Linux 6.5.
So I try installing the latest module from matplotlib source using 'python easy_install'.
#*scl enable python33 'bash'*
#*easy_install -m matplotlib
*
The install finished fine, but I am still get this error when I tried to import matplotlib. Is there anything else that I need to config?
# scl enable python33 'python'
Python 3.3.2 (default, Mar 20 2014, 20:25:51)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import scipy
>>> import matplotlib
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
ImportError: No module named 'matplotlib'
Below is the console when I run "easy_install -m matplotlib".
*At the end, it says "Finished processing dependencies for matplotlib". 
Does that mean matplotlib is not really installed yet?*
Do I miss any steps?

Thanks,

Thank you all.
I am using Python 3.4.3.
I meant to include a pip list:
Assimulo (2.8)
decorator (4.0.2)
gmpy2 (2.0.7)
ipykernel (4.0.3)
ipython (4.0.0)
ipython-genutils (0.1.0)
ipywidgets (4.0.2)
Jinja2 (2.8)
jsonschema (2.5.1)
jupyter-client (4.0.0)
jupyter-core (4.0.4)

six (1.9.0)
sympy (0.7.6)
testpath (0.2)
tornado (4.2.1)
traitlets (4.0.0)
So, if the program works for Python 2.7 but not 3.4.3, maybe that is the
problem? Let me try to install Python 2.7 tonight and see what that does.

OS: Windows 8.1 Pro
matplotlib version: 1.4.3
where obtained: http://www.lfd.uci.edu/~gohlke/pythonlibs/
customizations: none
Sample Program: attached py file; this is a Physics homework problem; I
have the answers I need, but would like to fix the errors to be able to
label all lines.
Debug output in attached output.txt file
If you uncomment line 180, the error is reported as if it came from that
line even though there is no float64 on that line (savefig). If commented,
it does not report a line from my .py file...
If you make line 170 read as follows, the error goes away:
if (maxTerm<32):
This suggests to me that the additional labels for the 32, 64, 128, and 154
term runs is what is triggering the bug, but I cannot figure out what it
is.
Also, separate note, just about any time I make figures, when closing the
last figure I get a python.exe app crash and this message:
alloc: invalid block: 00000000044E7680: 0 d
Thank you for any help,
Bobby
