Darrell, Thank you very much, the control is brilliant for my needs in getting this product out quickly, seems much faster than SVG generation too.

I was googling Binging this for days trying to find something like that, kept only coming across expensive controls

There is an ASP.NET Chart Control that you can download and use for free:

Check out the samples download too. The images on ScottGu's blog post aren't there anymore.

Also check out Alex Gorev's blog for the many things you can do with the Chart Control:

Dynamic Graphing in ASP.net

cronus89 — Fri, 03 Jul 2009 10:12:17 GMT

Hello,

Having recently moved to ASP.net from a more Applications based background, I am looking for some advice on Dynamic graphing.

I have a relatively large database of recorded values, taken at intermittent intervals over the course of a year, and I want to allow a user to enter two points in time and view a line chart of the values between those datas.

I have already done a similar thing in PHP, using SVG which was nice as it allowed me to add things like tooltips on points on the graph etc. SVG does however get very slow when lots of points are needed, and I would rather avoid it due to compatability issues.

Is there a good library already out there for graphing in ASP.net? I have looked into GD for drawing graphs, and while it is fast it provides as its output just image files which cannot really be interacted with.

Even better would be a control already out there that takes a dataset and draws me a nice chart...but I might be asking too much here...

All advice appreciated.

Adam
