title: Column Chart with DateTime on AxisX Displays wrong Dates
body: <p>I created a column chart and I simply don't get the labels on the X-axis right.</p>
  
  <p>Here is a screenshot of my chart. I added a line at the bottom of the screenshot to show how I expect it to be.</p>

  <p>Here is my code:</p>
  
  <pre><code>private void Form1_Load(object sender, EventArgs e)
  {
      string series = "TestData";
  
      // Clear Series
      chart.Series.Clear();
  
      // Add new Sereis and set XValueType
      chart.Series.Add(series);
      chart.Series[series].XValueType = ChartValueType.DateTime;
  
      // Add data points to Series
      chart.Series[series].Points.AddXY(new DateTime(2008, 12, 31).ToOADate(), 49.91);
      chart.Series[series].Points.AddXY(new DateTime(2009, 12, 31).ToOADate(), 102.05);
      chart.Series[series].Points.AddXY(new DateTime(2010, 12, 31).ToOADate(), 15.84);
      chart.Series[series].Points.AddXY(new DateTime(2011, 12, 31).ToOADate(), 29.12);
      chart.Series[series].Points.AddXY(new DateTime(2012, 12, 31).ToOADate(), 3.3);
      chart.Series[series].Points.AddXY(new DateTime(2013, 12, 31).ToOADate(), 31.09);
      chart.Series[series].Points.AddXY(new DateTime(2014, 12, 31).ToOADate(), 5.44);
  
      // Set color and dash style of Major Grid
      chart.ChartAreas[0].AxisY.MajorGrid.LineColor       = Color.Gray;
      chart.ChartAreas[0].AxisY.MajorGrid.LineDashStyle   = ChartDashStyle.Dash;
      chart.ChartAreas[0].AxisX.MajorGrid.LineColor       = Color.Gray;
      chart.ChartAreas[0].AxisX.MajorGrid.LineDashStyle   = ChartDashStyle.Dash;
  
      // Set Interval for X-Axis
      chart.ChartAreas[0].AxisX.LabelStyle.Format         = "yyyy";
      chart.ChartAreas[0].AxisX.Interval                  = 1;
      chart.ChartAreas[0].AxisX.IntervalType              = DateTimeIntervalType.Years;
      chart.ChartAreas[0].AxisX.IntervalOffsetType        = DateTimeIntervalType.Years;
  }
  </code></pre>
  
  <p>I already tried to use the <code>IntervalOffset</code>, but it did not do the job.</p>
  
  <p>Does somebody know how to fix this issue?</p>
  
  <p>Many thanks
  Konstantin</p>
