title: Obtaining a plot which shows the three quantities in a single point?
body: <p>Let's say I have a timeseries dataset for a particular quantity <code>Quantity</code>.</p>
  
  <p>In addition to that I also have two constant values <code>Q_low</code> and <code>Q_high</code> which represents the minimum and maximum values that <code>Quantity</code> can get. </p>
  
  <p>What I need to get is an error bar sort of plot which I can use to show the variation of <code>Quantity</code> within the lower and upper limit for the entire duration.</p>
  
  <p>Can anyone please help me how to obtain this sort of a plot in either matplotlib or MATLAB ?</p>
  
  <p>I tried using the box-plot but it will consider the min and max values depending on the dataset but not the user specified values.</p>
  
  <p>Thanks.</p>
