LightningChart Ultimate使用教程：在WPF中绘制点线数据

本教程讲述如何使用图表工具LightningChartUltimate PointLineSeries系列描绘变量区间点线数据。

学习该教程，你需要具备：

基本C#和Visual Studio 2010知识
安装LightningChartUltimate v5.1 （.NET4）
Visual Studio 2010或更高环境

1、添加LightningChartUltimate控件

建立一个WPF应用程序。在e Visual Studio工具栏中拖放组件"LightningChartUltimate"到表格窗口编辑器。

LightningChart Ultimate组件

窗口编辑器如下图：

LightningChart Ultimate窗口编辑器

代码如下：

									http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" title="MainWindow" height="350" width="525" xmlns:lcu="http://www.arction.com/schemas/">

2、初始化LightningChart组件

编辑MainWindow.xaml.cs源代码，用自定义外观设置和随机数据初始化。代码如下：

			
									/* Tutorial:
								
									* Simple LightningChart WPF application
								
									*/
								
									using System;
								
									using System.Collections.Generic;
								
									using System.Linq;
								
									using System.Text;
								
									using System.Windows;
								
									using System.Windows.Controls;
								
									using System.Windows.Data;
								
									using System.Windows.Documents;
								
									using System.Windows.Input;
								
									using System.Windows.Media;
								
									using System.Windows.Media.Imaging;
								
									using System.Windows.Navigation;
								
									using System.Windows.Shapes;
								
									using Arction.WPF.LightningChartUltimate;
								
									using Arction.WPF.LightningChartUltimate.Views.ViewXY;
								
									using Arction.WPF.LightningChartUltimate.SeriesXY;
								
									using Arction.WPF.LightningChartUltimate.Axes;
								
									//Make sure to use namespace similar to project name
								
									namespace Arction_tutorial1
								
									{
								
									/// 
								
									/// Interaction logic for MainWindow.xaml
								
									/// 
								
									public partial class MainWindow : Window
								
									{
								
									public MainWindow()
								
									{
								
									InitializeComponent();
								
									InitializeChart();
								
									}
								
									private void InitializeChart()
								
									{
								
									//Initialize chart
								
									lightningChartUltimate1.BeginUpdate();
								
									//Get XY view
								
									ViewXY chartView = lightningChartUltimate1.ViewXY;
								
									//Get default x-axis and set the range and ValueType
								
									AxisX axisX = chartView.XAxes[0];
								
									axisX.SetRange(0, 20);
								
									axisX.ValueType = AxisValueType.Number;
								
									//Get default y-axis and set the range.
								
									AxisY axisY = chartView.YAxes[0];
								
									axisY.SetRange(0, 100);
								
									//Add point line series
								
									PointLineSeries pls = new PointLineSeries(chartView, axisX, axisY);
								
									pls.PointsVisible = true;
								
									//Generate random data
								
									Random rand = new Random();
								
									const double dInterval = 1;
								
									int iPointCount = (int)((axisX.Maximum - axisX.Minimum) / dInterval) + 1;
								
									SeriesPoint[] aPoints = new SeriesPoint[iPointCount];
								
									for (int iPoint = 0; iPoint < iPointCount; iPoint++)
								
									{
								
									aPoints[iPoint].X = (double)iPoint;
								
									aPoints[iPoint].Y = 100.0 * rand.NextDouble();
								
									}
								
									//Assign the data for the point line series
								
									pls.Points = aPoints;
								
									//Add series to the PointLineSeries container in the view
								
									chartView.PointLineSeries.Add(pls);
								
									//Apply chart property changes, which causes chart to be painted
								
									lightningChartUltimate1.EndUpdate();
								
									}
								
									}
								
									}

编译并运行这个程序，结果如下图所示：
