javascript - dc.js 图表使用带有单击事件的新组函数重绘

Question

当其他图表库单击事件时，我尝试使用新组重绘 dc.js 图表。但它不会重绘。

这是我的 JavaScript 代码:

 var donemChart = dc.rowChart('div#donem'),
        hospitalTypeChart = dc.rowChart('div#hospital_type'),
        ckysHospitalClassChart = dc.rowChart('div#ckys_hospital_class'),
        ckysHospitalTypeChart = dc.rowChart('div#ckys_hospital_type'),
        hospitalHealthRegionChart = dc.rowChart('div#hospital_health_region'),
        hospitalRoleChart = dc.rowChart('div#hospital_role'),
        hospitalsChart = dc.rowChart('div#hospitals');




    d3.json('tsim.json',function(data){

        var ndx = crossfilter(data);
        var all = ndx.groupAll();




        //define crossfilter dimensions

        var donemDim = ndx.dimension(function(d){ return d.DONEM}),
                hospitalTypeDim = ndx.dimension(function(d){ return d.KURUM_TURU}),
                ckysHospitalClassDim = ndx.dimension(function(d){ return d.CKYS_KURUM_TURU}),
                ckysHospitalTypeDim = ndx.dimension(function(d){ return d.CKYS_KURUM_TIPI}),
                hospitalHealthRegionDim = ndx.dimension(function(d){ return d.SAGLIK_BOLGESI}),
                hospitalRoleDim = ndx.dimension(function(d){ return d.HASTANE_ROL}),
                hospitalsDim = ndx.dimension(function(d){return d.HASTANE}) ;

        var donemGroup = donemDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            hospitalTypeGroup = hospitalTypeDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            ckysHospitalClassGroup = ckysHospitalClassDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            ckysHospitalTypeGroup = ckysHospitalTypeDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            hospitalRoleGroup = hospitalRoleDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            hospitalsGroup = hospitalsDim.group().reduceSum(function(d){return d.toplam_muayene_say}),
            hospitalHealthRegionGroup = hospitalHealthRegionDim.group().reduceSum(function(d){return d.toplam_muayene_say});

当单击图表时，我在图表监听器函数中检查数据类型后获取数据类型。并且我将维度与新组分组。当它是控制台记录时，新组显示，但不会影响重新绘制图表.

这个问题我该怎么办？我们该如何解决这个问题？

谢谢

您刚刚将 hospitalTypeGroup 变量的引用(例如)重新分配给另一个对象。但图表仍然保留对旧对象的引用。您必须使用 hospitalTypeChart.group(hospitalTypeGroup) 重置 hospitalTypeChart 上的组，然后重新渲染。 (我认为在很多情况下重绘在这里不起作用。)
