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
最佳答案
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。)
关于javascript - dc.js 图表使用带有单击事件的新组函数重绘，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35059940/
