title: Plotting two different arrays of different lengths
body: <p>I have two arrays. One is the raw signal of length (1000, )  and the other one is the smooth signal of length (100,). I want to visually represent how the smooth signal represents the raw signal. Since these arrays are of different length, I am not able to plot them one over the other. Is there a way to do so in matplotlib?</p>
  
  <p>Thanks!</p>
