New and improved this morning, we have a two-fer.

First, on the extend plugin directory, you may notice some new pie chart fun on the stats tab for each plugin. This shows a percentage breakdown of the versions being actively used by that plugin’s users. Only slices greater than 1.0% are shown.

Secondly, since data kept in a box is not very useful, there’s a new API for getting this data. Usage is fairly obvious from just a simple example, which gets the version breakdown of one of my own plugins:

http://api.wordpress.org/stats/plugin/1.0/simple-facebook-connect?callback=demo

The callback parameter is optional, of course, and provided for people who want JSONP usage.

Note that the version data is relatively new, so we don’t have it for all plugins at present. It will get better as reporting continues. For those interested, it’s saving the total counts of the version numbers as reported by the plugin update-checks over the last week. Since the data at present is only from one day, it’s not very accurate.
