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; |
Created attachment 666 [details] 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.Chart3DPercent = 90; tChart1.Aspect.Elevation = 348; tChart1.Aspect.Orthogonal = false; tChart1.Aspect.Perspective = 62; 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; } } //output 4.1.2016.10260 depth: 0, Infinity?
