How add plots to subplots using matplotlib

Question

I want to add plots to subplots using

fig, axarr = plt.subplots(2, 2)
plt.sca(axarr[0, 0])
result = desire_salary.pivot_table('city', 'cult', aggfunc='count')
axarr[0, 0] = result.plot(kind='bar', alpha=0.75, rot=0, label="Presence /         Absence of cultural centre")
axarr[0, 0].set_xlabel("Cultural centre")
axarr[0, 0].set_ylabel("Frequency")
axarr[0, 0].set_title('Salary and culture')
axarr[0, 0].plot(result[[0]], color='red')
plt.sca(axarr[0, 1])
axarr[0, 1] = df.plot()
plt.sca(axarr[1, 0])
plt.show()

But one added to subplot, but others no. I get What I do wrong?

How about replacing axarr[0, 1] = df.plot() with df.plot(ax=axarr[0, 1])? — SparkAndShine

When you use pandas (I assume), the surest way to ensure which axes is used is to pass the reference to the axes to the plotting function using the ax= parameter

fig, axarr = plt.subplots(2, 2)
result = desire_salary.pivot_table('city', 'cult', aggfunc='count')
result.plot(kind='bar', alpha=0.75, rot=0, label="Presence /         Absence of cultural centre", ax=axarr[0, 0])
axarr[0, 0].set_xlabel("Cultural centre")
axarr[0, 0].set_ylabel("Frequency")
axarr[0, 0].set_title('Salary and culture')
axarr[0, 0].plot(result[[0]], color='red')


df.plot(ax=axarr[0, 1])

plt.show()

Why if I chenge fig, axarr = plt.subplots(2, 2) to fig, axarr = plt.subplots(2, 1), it returns ` plt.sca(axarr[0, 1]) IndexError: too many indices for array`?

if you do fig, axarr = plt.subplots(2, 1) you only have 2 subplots on 2 rows, 1 column. In that case subplotsreturns a 1 dimension array, so the valid indices are axarr[0] and axarr[1]

but if I want 3 plots? 2 at the top and 1 at the bottom?
