  +Additionally, you can have as many other columns as you want: these will be treated as subcategories in your data and you will be able to filter them.

positive.code: |Description
  |Required?
  
  |pivot
  |Subcategory in your data
  |No
  
  |day
  |X values (date or datetime)
  |Yes
  
negative.code: * **report1**, **report2**, etc.: report name (from the configuration). The number determines in which slot the data should be displayed, starting from the top of the page. For example, report1=trials&report1=conversions&report1=cancellations&report2=accounts will graph the trials, conversions and cancellations reports in the first slot (on the same graph), and the accounts report below (in slot 2)
  * **startDate** and **endDate**: dates to filter the data on the server side. For example: startDate=2012-08-01&endDate=2013-10-01
  * **smooth1**, **smooth2**, etc.: smoothing function to apply for data in a given slot. Currently support smoothing functions are:
  ** AVERAGE_WEEKLY: average the values on a weekly basis
  ** AVERAGE_MONTHLY: average the values on a monthly basis
  ** SUM_WEEKLY: sum all values on a weekly basis
  ** SUM_MONTHLY: sum all values on a monthly basis
  * To filter subcategories from a report, use *|* to create a filter (think of it as a UNIX pipe) and use *=* and *!=* for inclusions and exclusions respectfully. For example, assuming your report *payments_per_day* includes a *currency* column, report1=payments_per_day|currency=AUD|currency=EUR will graph the payments for AUD and EUR only, whereas report1=payments_per_day|currency!=AUD|currency!=EUR will graph all payments but the ones in AUD and EUR.
  
  To continue with our example above, you can see the report by going to http://127.0.0.1:8080/plugins/killbill-analytics/static/analytics.html?report1=new_accounts_per_day[http://127.0.0.1:8080/plugins/killbill-analytics/static/analytics.html?report1=new_accounts_per_day].
