I have two python lists - a (entries are strings) and b (numerical). I plot them with the following snippet (works perfectly) - 

import matplotlib.pyplot as plt
plt.bar(names, values)
plt.suptitle('Average Resale Price (SGD) vs Flat Model')
plt.xticks(rotation='82.5')
plt.show()

Now I try to save the above figure - 

plt.savefig('foo.png',dpi=400)

However I end up getting a white figure! How do I save the barplot ?

  • What else have you tried? Why do you expect this to work and it does not? – RaphaMex Dec 21 '17 at 03:37

    The python code halts when you call `plt.show()`, so I'm guessing that you are closing the figure before `plt.savefig` is being called -- it might be that this is the reason for the white figure. Try to comment out the `plt.show()` line and re-run the code. – Thomas Kühn Dec 21 '17 at 07:00

It's easy. Try to put plt.savefig('foo.png',dpi=400) before plt.show():

import matplotlib.pyplot as plot

names=['alex', 'simon', 'beta']
values=[10,20,30]

plt.bar(names, values)
plt.suptitle('Average Resale Price (SGD) vs Flat Model')
plt.xticks(rotation='82.5')

plt.savefig('foo.png',dpi=400)
plt.show()
