Brush not filtering when using composite chart

[gramster]

Is this supposed to work?

If I create a line chart with a data table, selecting an area of the chart with the brush filters the data in the table. If I take that same line chart and wrap it in a composite chart (even if it is the only chart in the composite), the data table no longer gets filtered.

My code is the same in each case except for this:

        dcl = dc.lineChart("#dc-chart");
        dcl.dimension(dateDim)
            .group(open, "Open");

versus:

        dcl = dc.compositeChart("#dc-chart");
        dcl.compose([
                dc.lineChart(dcl)
                    .dimension(dateDim)
                    .group(open, "Open")
      ]);

This is a duplicate of, well, a lot of things.

Please try it out and see if it helps. Will merge to develop soon.

Any news on this one?

This fixed it for me:

As of 2.0.0-beta32, CompositeChart's _chart._brushing() still does not trigger any redraw events. The google group link posted by Fil did not work for me.

A solution that worked for me is to simply comment out CompositeChart's _chart._brushing() function. This makes CompositeCharts use CoordinateGridMixin's _chart._brushing() for brushing, and works just fine.

Thanks @joysword, that sounds like a good workaround, as long as the dimension is the same for the composite and its children. I think we could make it possible to restore the overridden method without having to change the source.

@Fil updated for 404'd external resources http://jsfiddle.net/cBgkT/42/

The redefined _chart._brushing function works if the composite graph has the defined dimension but fails if the sub-charts have defined dimensions.

When I override the _chart._brushing() method I get unexpected behavior - the filtered set and brush jump around sporadically. Using 2.0.0-beta32.
