像彩票那样走势图要怎么做啊。。
给个思路。。或是简单说一下
[解决办法]
每两个数之间确定一条直线...
多分几个点,然后连上线行了.
[解决办法]
我以前用VML
感觉不错
只是他只能在IE下工作

彩票也有走势啊，那东西能算出来吗

可以用owc

图表组件wsChart4.6(DLL版)
[解决办法]
这是我以前写的一个画图的
用的是owc
输入参数是两个炼表
以其中之一作说明 MutiaxesX
MutiaxesX里面包含多个Arraylist
每一个记录了一条曲线的横轴的坐标
MutiaxesY同理，分别记录了这几条曲线的Y坐标
mapwidth可以设为800
高可以设为400
剩下两个word是图的title
show——mode对你来说没用
