title: Modification of the "Heat Maps of MSFT Adjusted Close
body: <p>I found very useful and complex figure from below link but the displays daily closing price by year for 4 years but my target figure is say 30 years daily closing price so it's too long and should be too messy for the readers.</p>
  
  <p><a href="https://stackoverflow.com/questions/2076370/most-underused-data-visualization">Most underused data visualization</a></p>
  
  <p>Instead, I want to transform the daily data as quarterly (on y axis) for 6 consecutive years (on x axis) but I can not transform year to 6 years on the following facet  </p>
  
  <pre><code>facet_wrap(~ year, ncol = 1)
  </code></pre>
  
  <p>as I a new to the ggplot2.     </p>
  
  <p>Can somebody have a look and give me the solution?</p>
  
  <p>Many thanks</p>
