请问怎么根据采样得到的300个左右的数据绘制曲线呢？

Question

我采样得到一组300个左右的数据，请问怎么将它绘制成曲线呢。需要绘制到PictureBox或者Panel面板控件上。对GDI+绘图了解很少，还请各位给些方法，最好能给点实例。

Answer 1

你想幹嘛，直接用工業控件顯示就可以了，你不知道OPC？連上去就OKhttp://www.iocomp.com

Answer 3

作图情况基本思路就是这样，你把list的数据换成你自己的就好了。有这么几步：
1.建立bitmap
2.用上bitmap建立graphics
3.用graphics的函数，和你的数据画图
4.picturebox.image=bimmap显示

Answer 4

还有一个困惑就是我不可能每个点都建立一个Point[]结构，这样上百个数据就得建立上百个Point[],然后再来调用绘图方法。请问具体是怎么用循环来实现的呢？
