title: MSChart: Label format
body: <p>How can I format chart label?
  I need to see only 2 digits after point.</p>
  
  <p>I try <code>chart.ChartAreas.First().AxisY.LabelStyle.Format = "#.##";</code> and <code>0.00</code></p>
  
  <p>Also I try to set <code>Series[0].LabelFormat = "0.00"</code> and <code>#.##</code></p>
  
  <p>and without success.</p>
  
  <p>What is wrong?</p>
