Not sure why this simple plot won't show. simply shows an In[*] and won't finish loading the plot. Can't find any info on what the * means. Any help?
import numpy as np
import matplotlib.pyplot as plt
r = np.arange(1,11)
v2 = 1.0/r
font = {'family' : 'serif',
'color' : 'black',
'weight' : 'normal',
'size' : 18,
}
plt.xlabel('$V*$', fontdict = font)
plt.ylabel('$Radii$', fontdict = font)
plt.plot(r,v2,lw=2)
plt.show()
Setting the iPython notebook %matplotlib magic command here is what you need to display the plot.
Basically, that command tells the notebook which backend to use when plotting with matplotlib, and sets it to work interactively. You usually will want to set that at the top of your notebook.
There are several options. A common one is
%matplotlib inline
which displays the plots right there in the iPython notebook.
Other options will depend on your system, but can include:
‘gtk’, ‘gtk3’, ‘inline’, ‘nbagg’, ‘notebook’, ‘osx’, ‘qt’, ‘qt4’, ‘qt5’, ‘tk’, ‘wx’
If you just set:
%matplotlib
without a gui option, it will use the default backend on your system (defined in your .matplotlibrc file).
%matplotlib inline
