Arction 图表控件 LightningChart.NET 如何具有鼠标点跟踪和注释的 3D 图表
1.将 View3D 定义为活动视图并定义 Z 轴范围。
// Set View3D as active view and set Z-axis range.chart.ActiveView = ActiveView.View3D;chart.View3D.ZAxisPrimary3D.SetRange(0, 80);
2.创建一个新的 PointLineSeries3D 对象以显示数据。
// Create a new PointLineSeries3D for displaying data and set axis bindings to primary axes.var series = new PointLineSeries3D(chart.View3D, Axis3DBinding.Primary, Axis3DBinding.Primary, Axis3DBinding.Primary){// Set this to true to set a color for individual points.IndividualPointColors = true,// Set this to true in order for mouse tracking to work.MouseInteraction = true};
3.将样式应用于新创建的系列。
// Set a title to the series.series.Title.Text = "Series 0";
// Set point shape to a sphere.series.PointStyle.Shape3D = PointShape3D.Sphere;
// Set individual point size.series.PointStyle.Size3D.SetValues(3, 3, 3);
// Set the width of the line between points.series.LineStyle.Width = 0.4f;
// Draw the line between points with the same color as the points.series.LineStyle.LineOptimization = LineOptimization.NormalWithShading;
// Set a color to the line.series.LineStyle.Color = Color.FromArgb(255, 255, 0, 0);
4.为数据点创建 SeriesPoint3D 数组并添加数据。
// Create a SeriesPoint3D array for data points.SeriesPoint3D[] points = new SeriesPoint3D[10];
// Generate sample data to the array.for (int j = 0; j < 10; j++) { // Random values for data points. points[j].X = 5 + j * 10; points[j].Y = 30 + random.NextDouble() * 25.0; points[j].Z = 10 + i * 10; // You can set an individual color to each point with the Color property. points[j].Color = Color.FromArgb(255, 255, 0, 0); } // Set the points array to series Points property. series.Points = points; // Add the series to chart's View3D. chart.View3D.PointLineSeries3D.Add(series);
5.创建一个注释以显示鼠标跟踪值
// Create a new annotation to display target values when hovering over a point with the mouse.mouseAnnotation = new Annotation3D(chart.View3D, Axis3DBinding.Primary, Axis3DBinding.Primary, Axis3DBinding.Primary){// Set the annotation as invisible by default.Visible = false,
};
// Set offset to annotation.mouseAnnotation.LocationRelativeOffset.SetValues(40, -70);
// Add annotation to View3D.chart.View3D.Annotations.Add(mouseAnnotation);
6.将 MouseMove 事件处理程序添加到图表中以启用点跟踪
chart.MouseMove += Chart_MouseMove;
7.为鼠标移动事件处理程序创建一个函数
private void Chart_MouseMove(object sender, System.Windows.Input.MouseEventArgs e){// Call BeginUpdate for chart to disable rendering while mouse is moving// over the chart to improve performance.chart.BeginUpdate();
