通常我们做统计图的时候需要借助组件来完成例如mschart,aspchart等
但是这个类不需要任何组件，而且使用方便
clsgraph.asp
<%
class inteligraph

public copyright, developer, name, version, web
public maximum, barwidth, barcolor, orientation
private items(), cnt

private sub class_initialize()
copyright = "?2001 ticluse teknologi, all rights reserved."
developer = "james lind雗"
name = "inteligraph"
version = "1.0"
web = "http://intelidev.com"
cnt = 0
end sub

public function add( value )
redim preserve items( cnt )
items( cnt ) = value
data = cnt
cnt = cnt + 1
add = data
end function

public function build()
if cnt < 1 then exit function
if len( orientation ) = 0 or lcase( orientation ) = "horizontal" then
for idx = lbound( items ) to ubound( items )
data = data & "" & vbnewline
data = data & vbtab & ""
if items(idx) < maximum then
data = data & ""
end if
data = data & "" & vbnewline & "" & vbnewline
next
elseif lcase( orientation ) = "vertical" then
data = "" & vbnewline
for idx = lbound( items ) to ubound( items )
data = data & "" & vbnewline
next
data = data & "

" & vbnewline if items(idx) < maximum then data = data & "" end if data = data & vbtab & "" data = data & "" & vbnewline & "" & vbnewline & "

" & vbnewline
end if
build = data
end function

end class
%>
使用方法
这个类一共有四个属性
barwidth（图片条的尺寸）
barcolor*(图片条颜色)
maximum（图片条最大长度）
orientation（方向）
有两个函数
add( value ）添加图片条到图片中
build()建立图片
事例：

<%
public const vert = "vertical"
public const horz = "horizontal"

dim graph

set graph = new inteligraph
graph.barwidth = 10
graph.barcolor = "blue"
graph.maximum = 100
graph.orientation = horz

for idx = 0 to 100 step 25
graph.add( idx )
next

response.write( graph.build() )
%>
