[ 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'.

| item | Object | The 'item' object allows you to style the active arrows within the chart history panel. For more information, see item. {...} |
| item-off itemOff | Object | The 'item-off' object allows you to style the inactive arrows within the chart history panel. For more information, see item-off. {...} |
| alpha | Numeric | Sets the transparency of the object. Values must range between 0.0 and 1.0, with 0.0 being completely invisible and 1.0 being completely opaque. Please note that values also require the leading 0 before the decimal. 0.3 | 0.9 | ... |

One color will set a solid background color; two colors will, by default, create a horizontal gradient.
