本文实例为大家分享了C# Chart绘制简单图形波形的具体代码，供大家参考，具体内容如下
此次用C#绘制波形使用的是Chart控件
1、将Chart控件拖进主界面，然后设置属性。

// // chart1// chartArea2.Name = "ChartArea1";this.chart1.ChartAreas.Add(chartArea2);legend2.Name = "Legend1";this.chart1.Legends.Add(legend2);this.chart1.Location = new System.Drawing.Point(36, 6);this.chart1.Name = "chart1";series3.BorderWidth = 3;series3.ChartArea = "ChartArea1";series3.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;series3.Legend = "Legend1";series3.Name = "系列1";series4.BorderWidth = 2;series4.ChartArea = "ChartArea1";series4.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;series4.Legend = "Legend1";series4.Name = "系列2";this.chart1.Series.Add(series3);this.chart1.Series.Add(series4);this.chart1.Size = new System.Drawing.Size(839, 499);this.chart1.TabIndex = 0;this.chart1.Text = "chart1"; |
2、画线委托函数

public delegate void ChartDelegate(int series, double Value_Y_Axis); // 声明委托public void DrawPoint(int series, double Value_Y_Axis){ try { if (this.chart1.InvokeRequired) { this.chart1.Invoke((ChartDelegate)DrawPoint, series, Value_Y_Axis); } else { this.chart1.Series[series - 1].Points.Add(Value_Y_Axis); } } catch { MessageBox.Show("ERROR!"); } //chart1.Series[series - 1].Points.Add(Value_Y_Axis);} |
3、设置一个按键，然后设置按键点击触发时候的定时器Timer属性，用来触发波形产生（用控件按键触发）

private void button3_Click(object sender, EventArgs e){ System.Timers.Timer timer11 = new System.Timers.Timer(400); // 每400ms触发一次 timer11.Elapsed += new System.Timers.ElapsedEventHandler(timer_handle); // 执行函数tiemr_handle timer11.AutoReset = true; timer11.Enabled = true; timer11.Start();} |
4、定时器触发执行函数

public int gIndex = 1;public void timer_handle(object source, System.Timers.ElapsedEventArgs e){ double mpre1 = Log10(gIndex) * 300; double mpre2 = Sin(gIndex) * 200; // DrawPoint(1, mpre1); DrawPoint(2, mpre2); gIndex++;} |
