Short Description
Client and server techniques for creating bar charts using tables that display in most browsers.

Long Description
Learn techniques for creating bar charts from standard HTML tables that work in all browsers. We use this technique for displaying the results of our discussion forum surveys (see results for target resolution survey). In this article, we provide both a server-based solution using VBScript and ASP as well as a client-side JavaScript object-based solution.

This article is <font size="3">GREAT</font>. There are a bunch of typos that will take some time to sort through, but for an ASP app that accesses a DB, the benfits are worth the time it takes to fix the code.

The generated barchart in the server-side script is invisible when printed. To solve this, create two gifs, darkgreen.gif and darkred.gif, and replace this first block of code:

str = str & "<TD valign=middle><TABLE><TR><TD bgcolor="
    ' Set bar color
    if iPercent > 50 then
      str = str & "darkgreen"
    else
      str = str & "darkred"
    end if
    str = str & "><IMG SRC='/gifs/s.gif' width=" & ((iPercent/100)*barSize) & " height=5>"

with this:

str = str & "<TD valign=middle><TABLE><TR><TD>"

' Set bar color
if iPercent > 50 then
       gif = "'darkgreen.gif'"
     else
       gif = "'darkred.gif'"
     end if

str = str & "<IMG SRC=" & gif & "width=" & ((iPercent/100)*barSize) & " height=5>"

Really nice work, which saves network loading and server resources for images
generation from simple data.
What about making a Pie then ?
Compliments !
