sample project

run the below code in build 4.1.2016.10260 and 4.1.2016.05120
in 4.1.2016.10260 it returns infinity where as 4.1.2016.05120 and earlier returns non-infinity values.

I am also attaching a sample project, run it in debug to see the output for the above versions.

public partial class Form1 : Form
   {
      public Form1()
      {
         InitializeComponent();
      }

      private void button1_Click(object sender, EventArgs e)
      {
         Surface s = new Surface(tChart1.Chart);

         s.Add(1, 0.021277799637864005d, 1);
         s.Add(2, 0.03886656098240001d, 2);
         s.Add(3, 0.03886156098240001d, 3);
         s.Add(4, 0.021277399637864005d, 4);
         s.Add(1, 0.03886236098240001d, 1);
         s.Add(2, 0.03886356098240001d, 2);
         s.Add(3, 0.03986356092240001d, 3);
         s.Add(4, 0.03886356098240001d, 4);
         s.Add(1, 0.03886356098240001d, 1);
         s.Add(2, 0.021277799637864005d, 2);
         s.Add(3, 0.03886356058240001d, 3);
         s.Add(4, 0.03886356048240001d, 4);
         s.Add(1, 0.03886256098240001d, 1);
         s.Add(2, 0.03886156098240001d, 2);
         s.Add(3, 0.03886316098240001d, 3);
         s.Add(4, 0.03886351098240001d, 4);

         tChart1.Series.Add(s);
      }

      private void tChart1_GetAxisLabel(object sender, GetAxisLabelEventArgs e)
      {
         if (sender.Equals(tChart1.Axes.Depth))
         {
            double dv = double.Parse(e.LabelText);
            Debug.WriteLine("depth: {0}, Infinity? {1}", e.LabelText, double.IsInfinity(dv));
         }
      }

      private void Form1_Load(object sender, EventArgs e)
      {
         tChart1.Graphics3D.SmoothingMode = SmoothingMode.HighQuality;
         tChart1.Graphics3D.BufferStyle = BufferStyle.OptimizedBuffer;

         tChart1.Aspect.ClipPoints = true;

         tChart1.Aspect.Rotation = 329;
         tChart1.Aspect.SmoothingMode = SmoothingMode.HighQuality;
         tChart1.Aspect.TextRenderingHint = TextRenderingHint.ClearTypeGridFit;
         tChart1.Aspect.Zoom = 70;
         tChart1.Aspect.View3D = false;

         tChart1.Axes.Depth.MaximumOffset = 3;
         tChart1.Axes.Depth.MinimumOffset = 3;
         tChart1.Axes.Depth.Title.Font.Size = 7;
         tChart1.Axes.Depth.AxisPen.Width = 1;
         tChart1.Axes.Depth.Labels.Font.Size = 7;
         tChart1.Axes.Depth.Visible = true;
      }
   }

Comment 1 marc meumann 2016-11-29 06:14:07 EST 
Problem caused by increased precision of minimim axis increment value in latest release.

Fixed in code for next release. 

=======
Workaround available in current version:

Set Axis (in this case Depth) minimum increment value:

tChart1.Axes.Depth.MinAxisIncrement = 1e-50;
