Matplotlib histogram plot from Numpy histogram data

Of course Pandas provides a quick and easy histogram plot, but if you're fine-tuning your histogram data generation in NumPy, it may not be obvious how to plot it. It can be done in one line:

hist = numpy.histogram(df.ix[df["Gender"]=="Male","Population"],range=(50,90))
pandas.DataFrame({'x':hist[1][1:],'y':hist[0]}).plot(x='x',kind='bar')
