Class: c3.Plot.Zoomable
| Defined in: | js/c3-plot.coffee |
| Inherits: | c3.Plot |
Overview
A type of plot that allows panning and zooming.
You cannot currently zoom with an ordinal scale.
External Interface
In addition to the standard {c3.base c3 interface}, this chart adds:
- focus() - Zoom the chart to the specified domain. Will not fire zoom events.
Events
- zoom - Triggered when the user starts to zoom or pan. Passed with the current focus domain.
- zoomend - Triggered when the user finishes zooming or panning. Passed with the focus domain.
Extensibility
The h scale will adjust it's domain based on the current focus of the chart. The original domain can be retreived using the _origh scale.
