Making a lengend clickable

[NP]

Is it possible to make a line graph legend clickable?

Also can anyone point me to links/documentation for using allowHtml?
I've seen it mentioned in several places but I've been unable to find
the actual explanation of how to use it.

Thanks..

Currently, no.

That's an option of the Table chart, not the LineChart.

The 'select' event fires when the colored blocks in the legend are clicked.  When hooked into the event handler, the chart's #getSelection method should return a single-element array containing an object with a null 'row' property and a 'column' property corresponding it's index in the underlying DataTable/DataView.  See http://jsfiddle.net/XRwTT/

Neither the legend as a whole nor the individual text entries fire events in the API, though.  If you need to trigger events off of them, it is theoretically possible to do so using standard javascript to dig into the chart container's internal iframe's contents and hook events into the SVG components therein.  This can be problematic as: 

1) it is not easy to identify specific chart components

2) the internals of the charts can change without warning, breaking your code

3) IE uses VML charts instead of SVG, so you would need a separate code path to handle IE.

Note the the upcoming release will make the event file also when clicking the legend text (not only the colored box next to the legend text).
