We have an Alexa Graph.
March 19, 2009 – 3:15 pmAlexa is a site that ranks the popularity of websites. They rank your site against all the other sites in the world.

If the site has ever been in the top 100,000, they display a graph of how your rank changes over time. You can see the Trade Me page above has a nice graph.
Whereas, for instance, the software-for-trademe.co.nz page below has never had a rank below 100,000- so it does not have a graph.
