我正在尝试在其他图表库点击事件时使用新组重绘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});

当我点击图表监听器功能中的数据类型后点击图表我得到数据类型。我正在将维度与新组分组。当它是consol记录新组显示但它不会影响重绘图表
我该怎么办？我们怎样解决这个问题？

您刚刚将hospitalTypeGroup变量（例如）的引用重新分配给其他对象。但图表仍然保留对旧对象的引用。您必须使用hospitalTypeChart重置hospitalTypeChart.group(hospitalTypeGroup)上的论坛，然后重新渲染。 （我不认为重绘会在很多情况下起作用。）

您需要提醒已更改群组的dc.js.
仅创建具有相同名称的新维度和组不会替换它们。您还需要适当地为每个图表调用.group()。
此外，我不建议每次点击某些内容时创建新的组（或维度）。 Crossfilter会因每个新组的速度而变慢，因为所有这些组都需要响应每个过滤器操作。相反，请提前创建组，并将它们应用于单击处理程序。
