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;
     
 }
