demo：用代码动态创建C1Chart实例，然后动态设定线条数据，同样的数据，每设定一次，线条颜色都会变化(循环有规律)，线条的颜色是随机的吧，使用了random，所以随机值循环有规律？
1、demo截图
2、代码如下：
public partial class Form1 : Form
{
private List<List<PointF>> lstpot = new List<List<PointF>>();
private C1Chart chart;
public Form1()
{
InitializeComponent();
lstpot.Clear();
List<PointF> lst = new List<PointF>();
lst.Add(new PointF(1, 20));
lst.Add(new PointF(2, 22));
lst.Add(new PointF(3, 19));
lst.Add(new PointF(4, 24));
lst.Add(new PointF(5, 25));
lstpot.Add(lst);
lst = new List<PointF>();
lst.Add(new PointF(1, 8));
lst.Add(new PointF(2, 12));
lst.Add(new PointF(3, 10));
lst.Add(new PointF(4, 12));
lst.Add(new PointF(5, 15));
lstpot.Add(lst);
lst = new List<PointF>();
lst.Add(new PointF(1, 10));
lst.Add(new PointF(2, 16));
lst.Add(new PointF(3, 17));
lst.Add(new PointF(4, 15));
lst.Add(new PointF(5, 23));
lstpot.Add(lst);
lst = new List<PointF>();
lst.Add(new PointF(1, 16));
lst.Add(new PointF(2, 19));
lst.Add(new PointF(3, 15));
lst.Add(new PointF(4, 22));
lst.Add(new PointF(5, 18));
lstpot.Add(lst);
}
