在餘燼中實現直流圖表

Question

我已將dc插件添加到我的餘燼應用。 在我的HBS我已經添加

這裏是javascript代碼：

VAR數據= [

 {date: "12/27/2012", http_404: 2, http_200: 190, http_302: 100}, 
     {date: "12/28/2012", http_404: 2, http_200: 10, http_302: 100}, 
     {date: "12/29/2012", http_404: 1, http_200: 300, http_302: 200}, 
     {date: "12/30/2012", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "12/31/2012", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "01/01/2013", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "01/02/2013", http_404: 1, http_200: 10, http_302: 1}, 
     {date: "01/03/2013", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "01/04/2013", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "01/05/2013", http_404: 2, http_200: 90, http_302: 0}, 
     {date: "01/06/2013", http_404: 2, http_200: 200, http_302: 1}, 
     {date: "01/07/2013", http_404: 1, http_200: 200, http_302: 100} 
     ]; 
var ndx = crossfilter(data); 
var parseDate = d3.time.format("%m/%d/%Y").parse; 
data.forEach(function(d) { 
    d.date = Date.parse(d.date); 
    d.total= d.http_404+d.http_200+d.http_302; 
}); 

var dateDim = ndx.dimension(function(d) {return d.date;}); 
var hits = dateDim.group().reduceSum(function(d) {return d.total;}); 
var minDate = dateDim.bottom(1)[0].date; 
var maxDate = dateDim.top(1)[0].date; 

hitslineChart 
    .width(500).height(200) 
    .dimension(dateDim) 
    .group(hits) 
    .x(d3.time.scale().domain([minDate,maxDate])) 
    .yAxisLabel("Hits per day"); 

dc.renderAll(); 

如何寫這個控制器中的JavaScript代碼。？

Answer 1

您應該將上面的代碼封裝在組件中。

並將所有與DOM相關的代碼編入didInsertElement方法的組件類中。
