LightningChart 教程

1、此图是结果图例，显示温度冷热程度及数据

2、以下是绘制此图的源代码:

LightningChartUltimate_chart = new LightningChartUltimate();

           _chart.BeginUpdate();

           //Create Surface mesh

           _mesh = new SurfaceMeshSeries3D(v, Axis3DBinding.Primary,Axis3DBinding.Primary, Axis3DBinding.Primary);

           //CONTOURS

           _mesh.ContourLineType = ContourLineType3D.ColorLineByValue;

           _mesh.ContourLineWidth = 1.5;

           //WIREFRAME           

           _mesh.WireframeType = SurfaceWireframeType.Wireframe;

           _mesh.WireframeLineStyle.Width = 3;

           _mesh.WireframeLineStyle.Color = Color.FromArgb(20, Color.Black);

           _mesh.WireframeOffset.SetValues(0, 0, 0);

           //FILL

           _mesh.ColorSaturation = 80;

           _mesh.Fill = SurfaceFillStyle.PalettedByValue;        

           //Discontinuity is caused by surface mesh...end meeting each other, anddata is not fluently continous over that.

InitializePalette();

           double[,] x = null;

           double[,] y = null;

           double[,] z = null;

           double[,] values = null;

           CreateGeometryPipe(out x, out y, out z);

           CreateValuesWaterDrops(out values);

           UpdateMesh(x, y, z, values);

           v.SurfaceMeshSeries3D.Add(_mesh);

            v.YAxisPrimary3D.Units.Text ="°C";

            _chart.EndUpdate();

总结

等高线地形图可综合应用于判断通视情况，水系水文特征，气候特征，地形状况与区位的选择(点、线、面 )。此3D几何图是用来判断气候特征的，非常直观。
