使用交叉过滤器在 dc js 中对条形图的数据进行分组时遇到问题
Facing issues while grouping data for bar chart in dc js using crossfilter
`d3.json('dc_test_case.json', function(error, data) {
var data = data;
var ndx = crossfilter(data);
homeDim = ndx.dimension(function(d){
return d.Inning;
});
nameDim = ndx.dimension(function(d){
if(d.Inning === "England batting"){
return d.Name;
}
});
runName = nameDim.group().reduceSum(function(d) {
if(d.Inning === "England batting") {
return Number(d.Runs);
}
});
var England_batting = dc.barChart("#England_batting");
England_batting.width(700)
.height(480)
.gap(30)
.yAxisLabel(".", 50)
.xAxisLabel("U", 50)
.dimension(nameDim)
.group(runName)
.x(d3.scale.ordinal().domain(nameDim))
.xUnits(dc.units.ordinal)
.y(d3.scale.linear().domain([0, 200]))
.elasticY(true)
.renderHorizontalGridLines(true)
.renderTitle(true)
.brushOn(true);
dc.renderAll();
});
英格兰击球的条形图不正确，有数据错误。我想我不应该使用 reduceSum 来对数据进行分组。我不知道我应该使用什么...任何人都能解决这个问题...
下面给出了此代码的 json...

]我认为切换到以下内容：
runName = nameDim.group().reduceSum(function(d) {
if(d.Inning === "England batting") {
return Number(d.Runs);
} else {
return 0;
}
});
问题是，如果澳大利亚击球，您返回未定义，并且15 + undefined评估为 NaN .
另外：请在未来创建一个工作示例。我只能盯着这个，但我无法检查我的解决方案是否真的有效。如果你创建一个工作示例，你更有可能获得帮助。
