Real-time graphs

Question

Do you know of a graphing library similar to Google's Annotated Timeline( http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html) that can be updated in realtime with new data points? Either javascript or flash is ok.

Thanks!

Answer 1

A lot of the bigger charting libraries/toolkits will let you update the datasets in 'realtime', if by realtime you mean that you're able to call a function on the chart to introduce new points.

Check out:

• Flot - JQuery
• Dojo charting (tutorial)
• Flex Charting (blog post) - Flash

Answer 2

Yahoo YUI

Answer 3

OpenFlashChart2 supports this, by means of JavaScript or a configurable polling interval pulling data from a backend script.

Answer 4

You could also try FusionWidgets v3 which gives you a choice of several types of real time charts which are extensively customizable and very easy to handle.
