As a test, I have included jQuery sparklines in my February report on SharePoint blogs.
The sparklines are in the “Trend” column. They display, in bar type, the blog’s authority in the past 3 months. To build them I have combined the “HTML calculated column” with the jQuery sparklines plugin.
I have already provided a tutorial to include Google sparklines in SharePoint lists a couple months ago. The Google approach is very convenient, but its downside is that your data goes public, you send it on the Internet to get the charts in return. That’s why I am interested in this alternate option.
However, I need to do some more testing as I noticed a rendering issue. If you have more information on this plugin please let me know!
Update [03/03/09] The author of the plugin, Gareth Watts, has worked on the rendering issue I reported. It will be fixed in v 1.4.1 .
Update [04/02/09] v 1.4.1 is now available for download.
