title: Unproportional Bubble Chart with the size paramater
body: <p>I´ve created a bubble chart and I put in some testing values as follow:</p>
  
  <pre><code>    this.chart1.Series["blueBubble"].Points.AddXY(2, 3, 6);
      this.chart1.Series["redBubble"].Points.AddXY(1, 0, 7);
      this.chart1.Series["yellowBubble"].Points.AddXY(1, 3, 8);
  </code></pre>
  
  <p>As I put in the size of the particular bubble to the third parameter of AddXY function, the sizing is done in a completely wrong proportional representation. See picture:</p>

  <p>How can I change the bubble sizes to the right proposition representation?</p>
