title: Remove text Backgroundcolor in matlab plot
body: <p>I have added some text in my plot. But I want to move its background to be as all other background which is gray. I know the following:</p>
  
  <pre><code>'Backgroundcolor',[0.7 0.7 0.7]
  </code></pre>
  
  <p>However, [0.7 0.7 0.7] gives color different than the backgroud. How can I make it same ?!</p>
