function makechart(title, numarray, labelarray, color, bgcolor, bordersize, maxheight, maxwidth, addvalues)
Function makechart version 3

Jason Borovoy
title: Chart Title
numarray: An array of values for the chart
labelarray: An array of labels coresponding to the values must me present
color If null uses different colors for bars if not null all bars color you specify
bgcolor Background color.
bordersize: border size or 0 for no border.
maxheight: maximum height for chart not including labels
maxwidth: width of each column
addvalues: true or false depending if you want the actual values shown on the chart
when you call the function use : response.write makechart(parameters)

actually returnstring would be a better name
dim tablestring
max value is maximum table value
dim max
maxlength maximum length of labels
dim maxlength
dim tempnumarray
dim templabelarray
dim heightarray
Dim colorarray
value to multiplie chart values by to get relitive size
Dim multiplier
if data valid
if maxheight > 0 and maxwidth > 0 and ubound(labelarray) = ubound(numarray) then
colorarray: color of each bars if more bars then colors loop through
if you dont like my choices change them, add them, delete them.
colorarray = array("red","blue","yellow","navy","orange","purple","green")
templabelarray = labelarray
tempnumarray = numarray
heightarray = array()
max = 0
maxlength = 0
tablestring = "<TABLE bgcolor=" & bgcolor & " border=" & bordersize & ">" & _
"<tr><td><TABLE border=0 cellspacing=1 cellpadding=0>" & vbCrLf
get maximum value
for each stuff in tempnumarray
if stuff > max then max = stuff end if
next
calculate multiplier
multiplier = maxheight/max > populate array
for counter = 0 to ubound(tempnumarray)
if tempnumarray(counter) = max then
redim preserve heightarray(counter)
heightarray(counter) = maxheight
else
redim preserve heightarray(counter)
heightarray(counter) = tempnumarray(counter) * multiplier
end if
next

if not isNUll(color) then
