[ root » history ]
History is one of the common approaches to creating a drilldown chart. It works just like the back and forward buttons of an Internet browser. When a series URL attribute directs to another chart's JSON file, clicking on the plotted data will render the linked JSON packet. Including the chart history object allows the user to go back and forth between the loaded charts. Note that the 'history' object must be placed in the root, outside of 'graphset'.
