Question

大家好我正在尝试使用canvasJS绘制堆积条以跟随嵌套列表：

pepidstat=[[[2016, 61, 'Feb'], [2011, 367, 'Feb'], [2013, 83, 'Feb'], [2014, 89, 'Feb'], [2015, 106, 'Feb']], [[2016, 43, 'Jan'], [2011, 128, 'Jan'], [2013, 150, 'Jan'], [2014, 74, 'Jan'], [2015, 121, 'Jan']]]

我可行的javascript是：

<script type="text/javascript">
  window.onload = function () {
    var chartbar = new CanvasJS.Chart("chartContainerBar",
    {
      title:{
      text: "Yearly Growth of Total Peptides"
      },
      animationEnabled: true,
      axisX: {
    interval: 1,
    labelFontSize: 10,
    lineThickness: 0
      },

      data:pepiddata
    });

    chartbar.render();
    chartbar={};
  }
  var pepidstatlist = {{ pepidstat|safe }};
  var pepiddata = [];var pepiddataSeries = { type: "stackedBar",showInLegend: "true" };
  var pepidname= [];
  var pepiddataPoints = [];
  for (pi = 0; pi < pepidstatlist.length;pi++) {
    piname = pepidstatlist[pi][0][2];
    for (pj = 0; pj < pepidstatlist[pi].length;pj++) {
      pidx=pepidstatlist[pi][pj][0];
      pidy=pepidstatlist[pi][pj][1];
      pepiddataPoints.push({
    x:pidx,      
    y: pidy,
    label: pidx,
    name:piname,
    toolTipContent: "{name}-{label}:{y}",   
      });
    }
    pepiddataSeries.name = piname; // here I want pass each month name

  }
  pepiddataSeries.dataPoints = pepiddataPoints;
  pepiddata.push(pepiddataSeries); 
  </script>

此脚本工作正常，但我无法在数据系列中指定每个月的名称。你能否建议我在哪里修改我的脚本？感谢

您只是创建一个dataSeries。创建两个dataSeries并将其推送到数据。其他一切都很好。

＆＃13;

 
pepidstat=[[[2011, 61, 'Feb'], [2012, 367, 'Feb'], [2013, 83, 'Feb'], [2014, 89, 'Feb'], [2015, 106, 'Feb']], [[2011, 43, 'Jan'], [2012, 128, 'Jan'], [2013, 150, 'Jan'], [2014, 74, 'Jan'], [2015, 121, 'Jan']]]

var pepidstatlist = pepidstat;
var pepiddata = [];
var pepidname= [];

for (pi = 0; pi < pepidstatlist.length;pi++) {
	piname = pepidstatlist[pi][0][2]; //month 
  var pepiddataPoints = [];
	for (pj = 0; pj < pepidstatlist[pi].length;pj++) {  
		pidx=pepidstatlist[pi][pj][0]; //Year
		pidy=pepidstatlist[pi][pj][1]; //value
		pepiddataPoints.push({
    	x:pidx,      
    	y: pidy,
    	label: pidx,
    	name:piname,
    	toolTipContent: "{name}-{label}:{y}",   
		});
	}
  var pepiddataSeries = { type: "stackedBar", showInLegend: "true" };
	pepiddataSeries.name = piname; // here I want pass each month name
	pepiddataSeries.dataPoints = pepiddataPoints;
	pepiddata.push(pepiddataSeries);
}

var chartbar = new CanvasJS.Chart("chartContainer",
{
	title:{
		text: "Yearly Growth of Total Peptides"
	},
	animationEnabled: true,
	axisX: {
		interval: 1,
		labelFontSize: 10,
		lineThickness: 0
	},
	data: pepiddata,
});

chartbar.render();

＆＃13;

<script src="http://canvasjs.com/assets/script/canvasjs.min.js"></script>
<br/><!-- Just so that JSFiddle's Result label doesn't overlap the Chart -->
<div id="chartContainer" style="height: 360px; width: 100%;"></div>

＆＃13;

提示：根据数组中的年份值对数组进行排序。

使用javascript堆积条形图
