title: Chart in winform displaying wrong Point
body: <p>I have the following code.
  I have hardcoded the x and y values to test.
  And for some reason for the point (0,-0.5) it plots (1,-0.5)
  For the life of me I do not know what is going on, because if you try other values then the graph displays correctly.</p>
  
  <pre><code>foreach (var grp in q)
              {
                  point = new DataPoint();
                   Sum1 = grp.Sum1 &gt; 2 ? 2 : grp.Sum1;
                  Sum1 = Sum1 &lt; -2 ? -2 : Sum1;
  
                  Sum2 = grp.Sum2 &gt; 2 ? 2 : grp.Sum2;
                  Sum2 = Sum2 &lt; -2 ? -2 : Sum2;
  
                  point.XValue = 0;
                  point.YValues = new double[] { -0.5 };
  
                  chart1.Series.Add(grp.Id.ToString());
                  chart1.Series[grp.Id.ToString()].ChartType = SeriesChartType.Point;
                  chart1.Series[grp.Id.ToString()].Label = grp.Id.ToString();
                  chart1.Series[grp.Id.ToString()].Points.Add(point);
                  chart1.Series[grp.Id.ToString()].ToolTip = "THEMES = " + Sum1 + "\n PRICES = " + Sum2;
                  chart1.Series[grp.Id.ToString()].LabelToolTip = "THEMES = " + Sum1 + "\n PRICES = " + Sum2;
                  chart1.Series[grp.Id.ToString()].MarkerSize = 11;
  
                  chart1.Update();
  
                  if (grp.Id.ToString() == "WW" || grp.Id.ToString() == "PB"
                      || grp.Id.ToString() == "AJ" || grp.Id.ToString() == "AK")
                  {
                      avgTheme += (float)Sum1;
                      avgPrice += (float)Sum2;
                      count++;
                  }
              }

  <p>UPDATE:</p>
  
  <p>this line needed to be added, works only with .NET 4.5</p>
  
  <pre><code>          chart1.Series["ABC"].CustomProperties = "IsXAxisQuantitative=True";
