一个大方的男孩送你200分！快来吧，犹豫什么呢？(200分)

怎样作坐标图？
现有数组A，I=20 我想用VB6.0来在坐标系统里动态地显示出来
请问各位大侠怎么编程，请附上源程序，好吗？
还有mschart怎么用。

你问完问题是不是就不来了?
那样请注销你的帐号

要源程序? 那你不久什么都不用做了么.
be a programmer!

哥们儿，这儿是讨论delphi的地方

你干嘛不到VB的论坛上去问

呵呵，你用delphi中的teechart就可以实现你的功能，
delphi中也有demo。

大家态度友善一点吧，不就是找错了门罢了！^o^

delphi里用teechart空间就行了。

首先，新建一个窗体，名称frmmain，上面加一个picturebox，名称为picpaint
加一个按钮，双击，代码如下：
Option Explicit

Private Declare Function SelectObject Lib "gdi32" (ByVal hDC As Long, ByVal hObject As Long) As Long
Private fnt As CLogFont



Private x(1 To 8) As Single
Private y(1 To 8) As Single
Private xcaption As String
Private Ycaption As String
Private n As Integer

Public Xo As Single
Public Yo As Single
Public Xlast As Single 'X 轴终点坐标
Public Ylast As Single 'Y 轴终点坐标

来了就好。

用Delphi吧！

for i:=1 to 20 do
begin
...
TChart.Series.Add( A )
...
end

// Easy !!!!
