You can also use svg to draw dynamic graphs in asp, but you'll have to learn a bit of svg to do it! Look at http://www.w3.org/TR/SVG/ for the specification. Users will have to download an svg plugin aswell (adobe svg), but that does not take long.
Basically, what you'll need to do in order to do graphs this way is create an asp file with the header and content something like;
<%
Option Explicit
%><?xml version="1.0"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20010904//EN"
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<svg xmlns="http://www.w3.org/2000/svg">
%>
<g id="db-symbol" style="stroke:#000000;">
<rect x="10" y="10" width="20" height="20">
</g>
</svg>
This would (should, I havn't tested it) simply draw a rectangle. With a little bit of work you can display anything including graphs, and of course, you can set any of the fields such as the width or height to be dynamic within asp, so you can have dynamic graphs.
You can then call the above code from any page where you would like to see it with something like:
<object type=""image/svg+xml"" data=""graph-horizbar.asp"
</object>
This is prob. the best way to do produce graphs within asp since you can get the graphs to look as nice as you like, and they will display on any browser that will install the svg plugin. The only problem is that you need to make all the drawing calculations to draw the graph yourself..
