I tried to run this code in spyder IDE of anaconda but it's not working
import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[1,4,9,16,25])
plt.show()
The above code is returning error as follows:
TypeError: 'tuple' object is not callable
I am not able to figure out the problem.Please help
Not sure if this applies here but I had similar issues with matplotlib. From another Stackoverflow-answer this suggestion helped me:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
As said in the comments: the full error would help figuring out what really goes wrong.

I am trying to create an animation using matplotlib. This requires that I import FuncAnimation. When I run
from matplotlib.animation import FuncAnimation
I get the following error:
CalledProcessError: Command '['convert', '--version']' died with <Signals.SIGABRT: 6>.
I am not sure what the issue is. I am using matplotlib 3.1.2. Is there any way to address this issue? Your feedback would be greatly appreciated.
I'm trying to run a basic matplotlib script to ensure that everything is working. The program is as follows:
import numpy as np
import matplotlib.pyplot as plt
x=np.arrange(0,5,0.1);
y=np.sin(x)
plt.plot(x,y)
But when I run "python a.py" in the terminal I am getting the error
that the numpy module has no attribute 'arrange'.
I uninstalled numpy and matplotlib and reinstalled them. First numpy, then matplotlib through the ubuntu repository but I am still getting this error. I can't figure out what is wrong. Am I getting an incomplete installation or something? I am using Ubuntu 14.04.
The method name is arange, not arrange.
Also, after using plt.plot(...), you need to call plt.show() to draw the plot.
I am trying to set a style in matplotlib as per tutorial http://matplotlib.org/users/style_sheets.html
import matplotlib.pyplot as plt
plt.style.use('ggplot')
but what I get in return is:
AttributeError: 'module' object has no attribute 'style'
My matplotlib version is 1.1.1 (and I'm on a Mac running Mavericks). Where are the styles in this version?
thanks!
My matplotlib version is 1.1.1
There's your problem. The style package was added in version 1.4. You should update your version.
In ipython notebook I also had to include %matplotlib inline, otherwise I would still get the same error.
%matplotlib inline
import matplotlib
matplotlib.style.use('ggplot')
For people using matplotlib 2.x and discovering this question can use the following snippet:
import matplotlib.style
import matplotlib as mpl
mpl.style.use('classic') # any style.
This is described in the documentation here. Note the import matplotlib.style is important.
I tried all solutions listed on StackOverflow but somehow none of these work for me. Finally I found a method which worked. Following are the details:
Environment:
OS : Ubuntu 16
Python Version : 3.5.
MatPlotLib Version : 2.0.2
Correct Way of importing 'style module'
import matplotlib
matplotlib.use
import matplotlib.pyplot as plt
plt.style.use('ggplot')
The matplotlib help reads:
:func:~matplotlib.use (ignore syntax as "`" did not work either on command line or script file)
a function for setting the matplotlib backend. If used, this
function must be called immediately after importing matplotlib
for the first time. In particular, it must be called
before importing pylab (if pylab is imported).
Somehow without issuing this command, it was not possible to access the 'Style' module.
Hope this helps.
For MatPlotLib version 3.6.3 and above, the following code to be used to use "seaborn" style as the seaborn has been deprecated since version 3.6:
import matplotlib
matplotlib.use
import matplotlib.pyplot as plt
plt.style.use("seaborn-v0_8")
Quite new to python and programming and tried to search for answers to matplotlib plots, but couldn't find answers to my question.
I use Spyder and have anaconda installed. Installed matplotlib but when i run simple plot commands I just get <"matplotlib.figure.Figure at 0x11090c18"> and no plot
If I run it in a dedicated python interpreter i just get an empty plot
The simple code is:
from matplotlib import pyplot as plt
plt.plot([1,2,3,4,5], [2,4,6,8,10])
plt.show()
Is this just the result of some stupid error I made in the installation process?
Hope someone can help med out
I think the error you're seeing is generated by a change the Matplotlib team did some months ago. I tried to fix it in Spyder 2.3.0/1 but maybe it's not working correctly.
To see a plot the code you need to run is
from matplotlib import pyplot as plt
plt.ion()
plt.plot([1,2,3,4,5], [2,4,6,8,10])
plt.show()
Notice the second line, that's what's needed to get interactive plots.
I seem to have a problem that is in parts very similar to the one mentioned here:
Python with eclipse import problem
But unfortunatly just in parts otherwise that would have solved mine as well.
I use Eclipse SDK, Version: 3.7.0 with PyDev 101.
Furthermore I have installed
numpy-1.6.1rc1-win32-superpack-python2.6.exe
and
matplotlib-1.0.1.win32-py2.6.exe
as noted here:
http://matplotlib.sourceforge.net/users/installing.html
I have rebuild all the packages and looks the site-packages are listed.
(by the way as you see it is an Python version installed with ArcGIS )
If I test a script for instance a very simple one like:
import numpy
import matplotlib
import pylab as pl
I get the following error in Eclipse:
import matplotlib
import pylab as pl
from matplotlib.pylab import *
ImportError: No module named pylab
Even though the interpreter for Pydev is pointing to the appropriate version of python and matplotlib is installed properly in there (site-packages) it does not work in Eclipse. In iPython it works perfect.
What still needs to be done to get matplotlib work in Eclipse?
Thanks a lot!

pylab is in matplotlibs namespace, so this should work:
import matplotlib.pylab as pylab
I found that turning off interactive move and then calling show worked.
import matplotlib.pyplot as plt
#...your code...
plt.ioff()
plt.show()
