dc.js 图表重绘与新的组功能与点击事件

Question

当其他图表库单击事件时，我正在尝试使用新组重绘 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}),

    });

当单击图表时，我在图表侦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。当它被 consol 记录时，新组显示但它不会影响重绘图表.

我能解决这个问题吗？我们如何解决这个问题？

谢谢

Answer 1

您刚刚将hospitalTypeGroup 变量的引用（例如）重新分配给了不同的对象。但是图表仍然持有对旧对象的引用。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都行不通。）

Answer 2

您需要提醒 dc.js 已更改的组。

仅创建具有相同名称的新维度和组不会替换它们。您还需要为每个图表适当地调用.group()。

另外，我不建议在每次单击某些内容时创建新组（或维度）。 Crossfilter 将随着每个新组而减慢速度，因为它们都需要响应每个过滤器操作。相反，请提前创建组并在点击处理程序中应用它们。
