Question

在将其他数据添加到crossfilter后，dc.js无法重绘图表。这是我的小提琴：http://jsfiddle.net/eugene_goldberg/v6j2ujrc/24/

$ua->simple_request()

有没有办法使这项工作？

经过一些搜索，遇到了一个小提琴（http://jsfiddle.net/eugene_goldberg/3tf725aL/2/），它有所需的技巧：

'option strict'
 var data = [{
    "key": "KEY-1",
    "state": "CA",
    "topics": ["Technology", "Science", "Automotive"],
    "date": new Date("10/02/2012")
}, {
    "key": "KEY-2",
    "state": "CA",
    "topics": ["Health"],
    "date": new Date("10/05/2012")
}, {
    "key": "KEY-4",
    "state": "WA",
    "topics": ["Automotive", "Science"],
    "date": new Date("10/09/2012")
}, {
    "key": "KEY-5",
    "state": "WA",
    "topics": ["Science"],
    "date": new Date("10/09/2012")
}

];

var cf = crossfilter(data);

var states = cf.dimension(function (d) {
    return d.state;
});
var stateGroup = states.group();

var pieChart = dc.pieChart("#piechart");
pieChart.height(75).width(75).dimension(states).group(stateGroup);


dc.renderAll();

setTimeout(function () {
    cf.add([{
        "key": "KEY-6",
        "state": "MD",
        "topics": ["Science"],
        "date": new Date("10/09/2012")
    }]);
    dc.redrawAll();
}, 1000);
