Flot Charts

I was asked to look for a graphing library for a web application project I am working on. After looking at several open-source libraries, I suggest the Flot library to the client.

It was very simple to set up initially, but there are a lot of configuration options, extensions and functionality for those willing to explore and delve a bit deeper. Over the last couple of weeks, I must say I am very impressed. We’re using standard time-based bar charts, line graphs, pie-charts and donuts.

Using an AJAX source allows for the graphs to be refreshed without having to reload the entire page. In addition, I extended the library to maintain both the original ‘raw’ data and a ‘displayed’ data which allows for further client-side modifications to the chart without having to retrieve additional data. Further development is on the horizon and I might get a bit of code added here for interested parties.

Here are a few examples. I definately recommend checking it out.
