We will be demonstrating Entrance Community version in booth 525 at the MySQ User Conference in Santa Clara. Stop by the booth and be sure to mention 'everythingmysql'.
and I think you will get the idea: Any MySQL SELECT command becomes a chart when you add Entrance PLOT.
Community version is GPLed. We can get help you get set up to both run and build it if you bring a laptop to the booth. (We can also show you the "Animated Shower Curtain" demo made almost famous by the LA MySQL Meetup)
