Pycharm does not show plot

Question

Pycharm does not show plot from the following code   import pandas as pd import numpy as np import matplotlib as plt  ts   pd Series np random randn 1000   index pd date range  1 1 2000   periods 1000    ts   ts cumsum       ts plot     What happens is that a window appears for less than a second  and then disappears again   Using the Pyzo IEP IDE  using same interpreter  on the same code the plot shows as expected      So the problem must be with some setting on Pycharm  I ve tried using both python exe and pythonw exe as interpreter both with same results   This is my sys info   C  pyzo2014a pythonw exe -u C  Program Files  x86  JetBrains PyCharm Community Edition 3 4 1 helpers pydev pydevconsole py 57315 57316 PyDev console  using IPython 2 1 0import sys  print  Python  s on  s     sys version  sys platform   Python 3 4 1  Continuum Analytics  Inc    default  May 19 2014  13 02 30   MSC v 1600 64 bit  AMD64   on win32 sys path extend   C   Users  Rasmus  PycharmProjects  untitled2    In 3   import IPython print IPython sys info      commit hash    681fd77     commit source    installation     default encoding    UTF-8     ipython path    C   pyzo2014a  lib  site-packages  IPython     ipython version    2 1 0     os name    nt     platform    Windows-8-6 2 9200     sys executable    C   pyzo2014a  pythonw exe     sys platform    win32     sys version    3 4 1  Continuum Analytics  Inc    default  May 19 2014                     13 02 30   MSC v 1600 64 bit  AMD64

I was able to get a combination of some of the other suggestions here working for me, but only while toggling the plt.interactive(False) to True and back again.

plt.interactive(True)
plt.pyplot.show()

This will flash up the my plots. Then setting to False allowed for viewing.

plt.interactive(False)
plt.pyplot.show()

As noted also my program would not exit until all the windows were closed. Here are some details on my current run environment:

Python version 2.7.6
Anaconda 1.9.2 (x86_64)
(default, Jan 10 2014, 11:23:15) 
[GCC 4.0.1 (Apple Inc. build 5493)]
Pandas version: 0.13.1

Soon after calling   plt imshow      call  plt show block   True    You will get the matplotlib popup with the image   This is a blocking way  Further script will not run until the pop is closed

For those who are running a script inside an IDE  and not working in an interactive environment such as a python console or a notebook   I found this to be the most intuitive and the simplest solution   plt imshow img  plt waitforbuttonpress     It shows the figure and waits until the user clicks on the new window  Only then it resume the script and run the rest of the code

Comment from DanT fixed this for me  matplotlib with pycharm on linux with the GTKagg backend  Upon importing matplotlib I would get the following error    gt  gt  gt  import matplotlib as mpl  Backend GTKAgg is interactive backend  Turning interactive mode on  Failed to enable GUI event loop integration for  gtk    When plotting something like so   from matplotlib import pyplot as plt plt figure   plt plot 1 2  plt show     A figure screen would pop up but no charts appear  using   plt show block True    displays the graphic correctly

I tried different solutions but what finally worked for me was plt show block True   You need to add this command after the myDataFrame plot   command for this to take effect  If you have multiple plot just add the command at the end of your code  It will allow you to see every data you are plotting

I tested in my version on PyCharm 2017 1 2  I used interactive  True  and show  block True    import pandas as pd import numpy as np import matplotlib pyplot as plt ts   pd Series np random randn 1000   index pd date range  1  2000  periods 1000   ts   ts cumsum   plt interactive True  ts plot   plt show block True

I test in my version of Pycharm  Community Edition 2017 2 2   you may need to announce both plt interactive False  and plt show block True  as following   import numpy as np import matplotlib pyplot as plt  x   np linspace 0  6 28  100   plt plot x  x  0 5  label  square root   plt plot x  np sin x   label  sinc    plt xlabel  x label   plt ylabel  y label    plt title  test plot    plt legend    plt show block True  plt interactive False

I had the same problem  Check wether plt isinteractive   is True  Setting it to  False  helped for me   plt interactive False

For beginners  you might also want to make sure you are running your script in the console  and not as regular Python code  It is fairly easy to highlight a piece of code and run it

I realize this is old but I figured I d clear up a misconception for other travelers  Setting plt pyplot isinteractive   to False means that the plot will on be drawn on specific commands to draw  i e  plt pyplot show     Setting plt pyplot isinteractive   to True means that every pyplot  plt  command will trigger a draw command  i e  plt pyplot show     So what you were more than likely looking for is plt pyplot show   at the end of your program to display the graph   As a side note you can shorten these statements a bit by using the following import command import matplotlib pyplot as plt rather than matplotlib as plt

In my case  I wanted to do the following       plt bar range len predictors    scores      plt xticks range len predictors    predictors  rotation  vertical       plt show     Following a mix of the solutions here  my solution was to add before that the following commands       matplotlib get backend       plt interactive False      plt figure     with the following two imports     import matplotlib    import matplotlib pyplot as plt   It seems that all the commands are necessary in my case  with a MBP with ElCapitan and PyCharm 2016 2 3  Greetings

With me the problem was the fact that matplotlib was using the wrong backend  I am using Debian Jessie   In a console I did the following   import matplotlib matplotlib get backend     The result was   agg   while this should be  TkAgg    The solution was simple    Uninstall matplotlib via pip  Install the appropriate libraries  sudo apt-get install tcl-dev tk-dev python-tk python3-tk Install matplotlib via pip again

Just use plt show    This command tells the system to draw the plot in Pycharm  Example  plt imshow img reshape  28  28    plt show
