C# Winform Chart控件用法2 多个chart动态曲线绘制

1、拖3个chart到新建的窗口中，分别命名为chart1,chart2,chart3,再放一个Button,如下图

2、对chart1的ChartAreas和Series属性进行相应的设置

ChartAreas ： 主要对游标和坐标轴进行设置，我们保持默认就可以。

其实大部。分的设置，都在Series属性进行，比如设置图标类型（样条曲线、散点、饼图...）、曲线数量、数据点标记样式、图例的名字等等

分别在chart1和chart2添加多一个Series，并在ChartType里设置图形样式，然后我们就可以分别往Series[0]和Series[1]添加数据了。

chart1.Series[0].Points.AddXY(i + 1, List_ia[i]); //添加数据

chart1.Series[1].Points.AddXY(i + 1, List_ic[i]); //添加数据

chart2相同的操作，只是设置图形样式都为Column分别添加数据后，效果如下
