Four things have made me appreciate Dygraphs:
- It's got an wide array of configurable options.
- It has an active community on the mailing list.
- The documentation continues to improve. The options listing above was a recent improvement that is now my regular go-to reference.
- The tests. Really I should call them examples. Because I can just often analyze them and get 80% of the way to the solution of the problem I'm working on.
If you need a graphing library I recommend you give Dygraphs a try.

What does this do that Google Chart Server doesn't? (http://code.google.com/apis/chart/index.html)
I'm just curious.
I don't really know chartserver. But I assume that because the charts are rendered natively rather than from a service you can do lots of nice interactive stuff with it, such as update live data:

Cool. I think you can accomplish the same thing with Chart Server API by updating the URL via javascript.
I really don't know anything about chart server. It sounds excellent, though.
We are using dygraphs (and Google Gauges) to monitor energy-efficient homes in New Hampshire.
Data is collected using wireless sensors, a web gateway pushes sensor data periodically to a web server. Data is logged using mySQL. Dygraphs is used to plot temperatures, relative humidity, HVAC runtimes, etc.

Dygraphs handles large amount of data much better than Google Charts.
