title: Plotting time in Python with Matplotlib
body: <p>I have an array of timestamps in the format (HH:MM:SS.mmmmmm) and another array of floating point numbers, each corresponding to a value in the timestamp array.</p>
  
  <p>Can I plot time on the x axis and the numbers on the y-axis using Matplotlib?</p>
  
  <p>I was trying to, but somehow it was only accepting arrays of floats. How can I get it to plot the time? Do I have to modify the format in any way?</p>
