attribute	description	on update
data	the data property used by chartist	uses chartist update method
type	type of chart, can be “Line”, ‘Bar”, or “Pie”	creates new chartist object
options	the options property used by chartist	uses chartist update method
responsive-options	the responsive-options property used by chartist	nothing *
chartist-events	custom element used to attach to emitted events	nothing

* currently not sure what to do when this changes or if it is supposed to change.

The custom attribute chartist-events allows you to handle any event fired by the eventemitter of chartist.

As seen in the above example, the draw event (a chartist event) will call the method animation and provide it with the data supplied by chartist.

If you installed a plugin for chartist which fires the foobar event, just add it in the same way and it will just work :-)
