Description christopher ireland 2014-04-14 04:18:50 EDT 
The following code illustrates the problem. Run the code then maximize the window - the chart is only rendered correctly after a zoom/unzoom operation.

        public Form1()
        {
          InitializeComponent();

          m_Chart.Aspect.View3D = false;
          m_RectangleX[0] = -50.0;
          m_RectangleY[0] = -50.0;

          m_RectangleX[1] = 50.0;
          m_RectangleY[1] = -50.0;

          m_RectangleX[2] = 50.0;
          m_RectangleY[2] = 50.0;

          m_RectangleX[3] = -50.0;
          m_RectangleY[3] = 50.0;

          m_RectangleX[4] = -50.0;
          m_RectangleY[4] = -50.0;

          m_Line.XValues.Count = 5;
          m_Line.XValues.Value = m_RectangleX;

          m_Line.YValues.Count = 5;
          m_Line.YValues.Value = m_RectangleY;

          m_Chart.Series.Add(m_Line);

          m_Chart.Axes.Bottom.Automatic = false;
          m_Chart.Axes.Bottom.Minimum = -100.0;
          m_Chart.Axes.Bottom.Maximum = 100.0;
          m_Chart.Axes.Bottom.Visible = false;
          m_Chart.Axes.Bottom.Ticks.Length = 0;

          m_Chart.Axes.Left.Automatic = false;
          m_Chart.Axes.Left.Minimum = -100.0;
          m_Chart.Axes.Left.Maximum = 100.0;
          m_Chart.Axes.Left.Visible = false;
          m_Chart.Axes.Left.Ticks.Length = 0;

          m_Line.IsoHorizAxes = true;

        }

May I have any updates on this bug?
Comment 2 christopher ireland 2014-05-02 05:01:15 EDT 
I'm afraid that this defect has not been fixed for the upcoming maintenance release, but will be given careful attention next week.
Comment 3 raavi.mohindar.rao 2014-05-07 05:16:17 EDT 
Thanks. 

Hope there is some solution in this week.

This is now fixed, and there is an effective workaround to this issue which only occurs when the axes are set to Visible=false. The workaround is the follows:

    private void InitializeChart()
    {
      Line m_Line = new Line(tChart1.Chart);
      double[] m_RectangleX = new double[5];
      double[] m_RectangleY = new double[5];

      tChart1.Aspect.View3D = false;
      m_RectangleX[0] = -50.0;
      m_RectangleY[0] = -50.0;

      m_RectangleX[1] = 50.0;
      m_RectangleY[1] = -50.0;

      m_RectangleX[2] = 50.0;
      m_RectangleY[2] = 50.0;

      m_RectangleX[3] = -50.0;
      m_RectangleY[3] = 50.0;

      m_RectangleX[4] = -50.0;
      m_RectangleY[4] = -50.0;

      m_Line.XValues.Count = 5;
      m_Line.XValues.Value = m_RectangleX;

      m_Line.YValues.Count = 5;
      m_Line.YValues.Value = m_RectangleY;

      tChart1.Series.Add(m_Line);

      tChart1.Axes.Bottom.Automatic = false;
      tChart1.Axes.Bottom.Minimum = -100.0;
      tChart1.Axes.Bottom.Maximum = 100.0;
      tChart1.Axes.Bottom.Visible = false;
      tChart1.Axes.Bottom.Ticks.Length = 0;

      tChart1.Axes.Left.Automatic = false;
      tChart1.Axes.Left.Minimum = -100.0;
      tChart1.Axes.Left.Maximum = 100.0;
      tChart1.Axes.Left.Visible = false;
      tChart1.Axes.Left.Ticks.Length = 0;

      m_Line.IsoHorizAxes = true;

      tChart1.BeforeDrawSeries += tChart1_BeforeDrawSeries;
    }

    void tChart1_BeforeDrawSeries(object sender, Graphics3D g)
    {
      tChart1.Axes.Bottom.AdjustMaxMin();
    }

Fixed: Confirmed. Works now.
