title: MS Chart Control Zoom MinSize issue
body: <p>I'm implementing a scatter plot using the MS Chart Control .NET 3.5, WinForms, C#.  My x-axis data is DateTime and noticed I couldn't zoom in smaller than a resolution of 1 day, despite setting the ScaleView as follows:</p>
  
  <pre><code>chart1.ChartAreas["MyChart"].AxisX.ScaleView.MinSize = 4;
  chart1.ChartAreas["MyChart"].AxisX.ScaleView.MinSizeType = DateTimeIntervalType.Hours;
  </code></pre>
  
  <p>Has anyone else had this issue?  Any ideas?</p>
