title: Different Background Color for each Chart quadrant
body: <p>Is there a way to paint each of the 4 quadrants with a different background color? I'm using BackColor but it paints the whole chart. I can't find how to customize by area, axis, or anything.</p>
  
  <pre><code>chart1.ChartAreas[0].BackColor = Color.AliceBlue;
  </code></pre>
  
  <p>this is my chart:</p>
  
  <p><img src="https://i.stack.imgur.com/87lJx.png" alt="This is my chart:"></p>
  
  <p>And I want it to look like this </p>
