Description (last modified by )
A heatmap is a graphical representation of data where the values taken by a variable in a two-dimensional map are represented as colors. Heatmap in this patch only works with canvas-enabled browsers, and shaped heatmap is supported. User can customize color trasition function.
var heatmap = new dojox.geo.charting.Heatmap("map"); var data = []; for (var i = 0; i < 120; i++) { data.push(getPoint()); } heatmap.setData(data); heatmap.render();
And there are 2 testcases in the patch.

update from Rock:
- change heatmap to a generic widget, it can be overlaid on normal element by given node/id;
- introduce "opacity" parameter to see the node under heatmap;

Didn't quite realize where this patch was, taking it from Eugene.

Based on the canvas-only approach, I don't think we can get this out for 1.6, particularly for dojox.charting (for which this was originally written). However, I *can* see taking the basic approach and using it as a basepoint for something a lot more generic.
In the future, I would recommend that if something can't be done using dojox.gfx (in terms of charting)...that we'd find a different place for it to live until it *can* be done using gfx.

Marking for future (i.e. until we get a patch that runs on IE), as per today's meeting discussion.

As ttrenka said, I think it should be moved out of charting into its own module. It should be moved to AMD as well.

Should be a community module/package instead of being added to DojoX at this point.
