Graphing Widget

The graphing widget shows graphs using the Rickshaw graphing library. The names of data fields should be (vaguely) familiar if you've used Rickshaw before.

It's recommended that you replace the /assets/javascripts/rickshaw.min.js from your dashboard with the latest from here.

Supported HTML data fields

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.
