Show a Pandas plot from a script

Question

I have a script (not an IPython notebook) that produces a plot at the end (via a pandas DataFrame). My problem is that such a plot is not showing.

Inspired by this I have tried

fig, ax = plt.subplots()
my_dataframe.plot(ax=ax)
ax.show()

which does not work. The only way I can show my plot is:

plt.figure()
my_dataframe.plot()
plt.show()

but this brings up also a empty figure that I don't want to have.

Answer 1

Did you try

fig, ax = plt.subplots()
my_dataframe.plot(ax=ax)
plt.show() # plt in place of ax
