Pandas plotting in Windows terminal

Question

I have a simple pandas data frame. Trying to plot from the Windows 10 terminal session of IPython gives me this:

In [4]: df = pd.DataFrame({'Y':[1, 3, 5, 7, 9], 'X':[0, 2, 4, 6, 8]})

In [5]: df
Out[5]:
   X  Y
0  0  1
1  2  3
2  4  5
3  6  7
4  8  9

In [6]: df.plot(kind='line')
Out[6]: <matplotlib.axes._subplots.AxesSubplot at 0x26c4d366940>

In [7]:

I can not see any plot. Is there something I’m doing wrong?

I think you can try add %matplotlib inline or ipython notebook --matplotlib inline for a notebook:

%matplotlib inline
#ipython notebook --matplotlib inline 
import pandas as pd
import matplotlib.pyplot as plt
    
df = pd.DataFrame({'Y':[1, 3, 5, 7, 9], 'X':[0, 2, 4, 6, 8]}) 

df.plot(kind='line')

Or you can add plt.show() for a console:

import pandas as pd
import matplotlib.pyplot as plt
    
df = pd.DataFrame({'Y':[1, 3, 5, 7, 9], 'X':[0, 2, 4, 6, 8]}) 

df.plot(kind='line')
plt.show()

Answer 2

Start your IPython session with the option --matplotlib:

ipython --matplotlib

This should give you a second window after this line df.plot(kind='line') and pressing <Enter>.:

You can keep the window open. For example:

In [4]: from matplotlib import pyplot as plt
In [5]: plt.title('Test')
Out[5]: <matplotlib.text.Text at 0x1124ed908>

Now you should see the title Test on your plot.
If it does not update try draw():

In [6]: plt.draw()
