will bar/treemap etc support selection status and select/unselect event like pie chart

[OliviaSong]

I've implemented the bar selection function, but I'm distressed about how to manage the code, so I ask if the Officialare considering implementing it，t's best to merge my code into the master

    var select=seriesModel.isSelected(data.getName(dataIndex));
    if(false===select)
    {
        color="#CDC5BF";
    }else{
        color = data.getItemVisual(dataIndex, 'color'); 
    }

this can keep unselectbar gray

Hi! Could you share how did you implement the bar chart selection? I need that to call a query to update charts only with selected bars, but I have no idea of how. Thanks a Lot
