title: Combining plt.plot(x,y) with plt.boxplot()
body: <p>I'm trying to combine a normal matplotlib.pyplot <code>plt.plot(x,y)</code> with variable <code>y</code> as a function of variable <code>x</code> with a boxplot. However, I only want a boxplot on certain (variable) locations of <code>x</code> but this does not seem to work in matplotlib?</p>
