C# Winform 入门（4）之动图显示

先看效果

---

1.搭建页面

Chart  控件      timer    button

Chart属性 Series =>   ChartType

• Cloumn   柱状图
• Point      点状图
• Area       面积图
• Pie          饼状图
• Candlestick    烛台形
• Radar     雷达
• Spline    线条曲线

 Timer  =>  Interval =>300

2. 实例化

List<double>dataForChatDisp=new List<double>() { 3,1,4,5,9};

3.封装表格方法 

 private void Disp_charts(){chart1.Series[0].Points.DataBindY(dataForChatDisp);chart2.Series[0].Points.DataBindY(dataForChatDisp);chart3.Series[0].Points.DataBindY(dataForChatDisp);chart4.Series[0].Points.DataBindY(dataForChatDisp);chart5.Series[0].Points.DataBindY(dataForChatDisp);chart6.Series[0].Points.DataBindY(dataForChatDisp);chart7.Series[0].Points.DataBindY(dataForChatDisp);}

4.随机生成实例

Random random = new Random();
double dataNext;

5.窗体加载

 private void Form1_Load(object sender, EventArgs e){timer1.Enabled=false;Disp_charts();}

6.计时器刻度

 private void timer1_Tick(object sender, EventArgs e){dataNext = random.Next(10);dataForChatDisp.RemoveAt(0);dataForChatDisp.Add(dataNext);Disp_charts();}

7.按钮功能实现

 private void btnforchat_Click(object sender, EventArgs e){timer1.Enabled = true;}
