我正在创建一个仪表板,数据格式如下:
var data = [
{"id": 'CDE', "count": 1, "name": 'ajdkf', "type": 'E', "state": 'A'},
{"id": 'CDE', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'A'},
{"id": 'CDE', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'A'},
{"id": 'CDE', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'A'},
{"id": 'HFG', "count": 1, "name": 'ajdkf', "type": 'E', "state": 'B'},
{"id": 'HFG', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'B'},
{"id": 'HFG', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'B'},
{"id": 'HFG', "count": 0, "name": 'ajdkf', "type": 'E', "state": 'B'},
{"id": 'ABF', "count": 1, "name": 'ghedw', "type": 'G', "state": 'A'},
{"id": 'ABF', "count": 0, "name": 'ghedw', "type": 'G', "state": 'A'},
{"id": 'ABF', "count": 0, "name": 'ghedw', "type": 'G', "state": 'A'},
{"id": 'ABF', "count": 0, "name": 'ghedw', "type": 'G', "state": 'A'},
{"id": 'DEF', "count": 1, "name": 'huiqs', "type": 'E', "state": 'A'},
{"id": 'DEF', "count": 0, "name": 'huiqs', "type": 'E', "state": 'A'},
{"id": 'DEF', "count": 0, "name": 'huiqs', "type": 'E', "state": 'A'},
{"id": 'DEF', "count": 0, "name": 'huiqs', "type": 'E', "state": 'A'},
...
{"id": 'ABC', "count": 1, "name": 'asbsd', "type": 'D', "state": 'B'},
{"id": 'ABC', "count": 0, "name": 'asbsd', "type": 'D', "state": 'B'},
{"id": 'ABC', "count": 0, "name": 'asbsd', "type": 'D', "state": 'B'},
{"id": 'ABC', "count": 0, "name": 'asbsd', "type": 'D', "state": 'B'}
];
我正在尝试创建一个看起来像这样的表:
Name State A Count State B Count
ajdkf 1 1
ghedw 1 0
huiqs 1 0
asbsd 0 1
我目前有:
<body>
<div style='clear:both;'>
<table id="Stats">
<thead>
<tr class="header">
<th> name </th>
<th> State A Count </th>
<th> State B Count </th>
</tr>
</thead>
</table>
</div>
</body>
<script>
...
var dataTable = dc.dataTable("#Stats");
var dataTableDim = ndx.dimension(function(d) {return d.name;});
dataTable
.dimension(dataTableDim)
.group(function(d) {return d.name})
.columns([
function(d) { return d.name; },
function(d) { if (d.state == 'A') {return +d.count;} else {return 0;} },
function(d) { if (d.state == 'B') {return +d.count;} else {return 0;} },
]);
...
</script>
它给了我一张看起来像的表:
Name State A Count State B Count
asbsd
asbsd 0 1
asbsd 0 0
asbsd 0 0
asbsd 0 0
ajdkf
ajdkf 1 0
ajdkf 0 0
ajdkf 0 0
ajdkf 0 0
ajdkf 0 1
ajdkf 0 0
ajdkf 0 0
ajdkf 0 0
huiqs
huiqs 1 0
huiqs 0 0
huiqs 0 0
huiqs 0 0
ghedw
ghedw 0 0
ghedw 1 0
ghedw 0 0
ghedw 0 0
我需要做些什么来获得我想要的桌子?我很想拥有A&#34; A&#34; 2&#39;列&#39; (计数和百分比)和状态B相同。
Name State A State B
Count Percent Count Percent

我无法读取外部文件的小提琴,所以我不得不将它们添加到j ..抱歉:((https://jsfiddle.net/56hgjgsz/29/)
这&#34;工作&#34;但是没有在表格中进行行减少而且排序是向后的 - &gt;相同的地址,但用/ 32 /而不是/ 14 /或/ 29 /
答案 0 :(得分:2)
在dc.js发布几年后,人们发现您实际上可以将组作为.dimension()
传递给数据表。这就是你想要的,因为你正在进行跨滤波器缩减以获得状态计数。
这是noted in the documentation here。
减少交叉过滤器组中多个值的方法是标准的:
var dataTableGroup = dataTableDim.group().reduce(
function(p, v) {
++p.number;
p.total += +v.count;
p.stateA += (v.state === 'A' ? v.count : 0);
p.stateB += (v.state === 'B' ? v.count : 0);
return p;
},
function(p, v) {
--p.number;
p.total -= +v.count;
p.stateA -= (v.state === 'A' ? v.count : 0);
p.stateB -= (v.state === 'B' ? v.count : 0);
return p;
},
function() {
return {
number: 0,
total: 0,
stateA: 0,
stateB: 0
}
}
);
然后我们可以制作一个假的维度&#34;使数据表读取顶部或底部N值,仅保留具有stateA
或stateB
值的容器。请注意,我们必须通过N
,与虚假组不同:
function remove_empty_bins_dt(source_group) {
return {
top: function(N) {
return source_group.top(N).filter(function(d) {
return d.value.stateA !== 0 || d.value.stateB !== 0;
});
},
bottom: function(N) { // hacky but should work
return source_group.top(Infinity).filter(function(d) {
return d.value.stateA !== 0 || d.value.stateB !== 0;
}).slice(-N).reverse();
}
};
}
同样,数据表在dc.js中是唯一的,因为它设计用于从交叉过滤器维度而不是组中读取数据。因此,我们需要将此假维度传递给.dimension()
而不是.group()
(which means something completely different叹气)

(如果我理解正确的话)
人们可以概括地看一下任意数量的字段,但今天我没有时间。
