[charting] events to plotter or series

[ttrenka]

From #1637:

Events -- even though it would be possible to attach event attributes to the raw SVG/VML nodes, it would be much less tedious and error-prone if this could be done at a much higher level, perhaps at the Series or Plotter level.

[ttrenka]

I'm going to set it up so that there's a stub function, at the Chart level, that will be fired on several different events. It should pass you the original event object, the marker node in question (if appropriate), and the actual data point the marker represents. You'd basically connect to the stub. For example:

dojo.connect(myChart, 'onmarkerclick', myFn); dojo.connect(myChart, 'onmarkermouseover', myFn);

etc.

Any thoughts, objections?

Looks good!

Reassigning to Eugene and removing the milestone.

IBM needs this interactivity in Dojo charts in 1.0.1. This API would enable us to, for example, make tooltips to display the series name (currently there is no identifier), or make XHR requests based on clicks to markers.

[peller]

how significant is this code change and what time frame might it be available? 1.0.1 is a bug fix release and might not be the most appropriate way to do this, especially depending on how we decide to structure dojox releases.

It is not difficult to add because the infrastructure is there. I just need some quality time with it, and I suspect the most time will be spent on testing.

Just out of curiosity: when is Dojo 1.0.1 going to be released?

[dylan]

I believe this is finished. Eugene, please confirm.

Moving all open ticketd to the future.
