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), in         


        

Answer 1

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)

Answer 2

One property need to set for pycharm.

import matplotlib.pyplot as plt

plt.interactive(False)  #need to set to False

dataset.plot(kind='box', subplots=True, layout=(2,2), sharex=False, sharey=False)

plt.show()

Answer 3

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.

Answer 4

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!

Answer 5

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.

Answer 6

In Pycharm , at times the Matplotlib.plot won't show up.

So after calling plt.show() check in the right side toolbar for SciView. Inside SciView every generated plots will be stored.
