How to create box plot from pandas object using matplotlib?

I read data into pandas object and then I want to create a box plot using matplotlib (not pandas.boxplot()). This is just for learning purposes. This is my code, in which myData['MyColumn'] fails.

import matplotlib.pyplot as plt
import pandas as pd

myData = pd.read_csv('data/myData.csv')

plt.boxplot(myData['MyColumn'])

plt.show()

Your code works fine with fake data. Check the type of the data you're trying to plot.

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
myData = pd.DataFrame(np.random.rand(10, 2), columns=['MyColumn', 'blah'])
plt.boxplot(myData['MyColumn'])
plt.show()
