Hi there,

I'm trying to generate this attached sort of chart.

• The data sits in an mysql database
• There are horizontal bars that show
  • in darker blue: current period's data
  • in lighter blue: last period's data
• left of it a delta view, i.e., the change between two periods
• there are data labels on the bart chart (to the right of the bars)

• there's a pie chart of the current period

• each slice of the pie and each bar should be clickable so as to parameterize the next report (drill down)

• the whole report should be parameterizable via URL
• the whole report should be exportable e.g. to pdf or png
• I need caching behind on top of the database (possible to use memcached?)
• what kind of authentication options are available?

Thanks!
