C#|C# Chart绘制简单图形波形 C#Chart绘制简单图形波形

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_handletimer11.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++; }
