eCharts-简单的堆叠折线图不显示数据

如何解决eCharts-简单的堆叠折线图不显示数据

我是eCharts的新手，我正在尝试使堆积式折线图正常工作。工具提示可以正确显示数据，但是没有y轴刻度，也没有线条或区域填充。如果我从“系列”部分中删除“堆栈：'a'”选项，则图表的非堆叠版本会正确显示。我的选择和数据如下：

var myChart = echarts.init(document.getElementById('main'));
        
var option = {
  "animation": false,"legend": {
    "show": true,"top": "middle","left": "right","orient": "vertical"
  },"title": {
    "text": "Total Raised by Type,Month and Year","left": "center"
  },"tooltip": {
    "trigger": "axis","axisPointer": {
      "type": "cross","label": {
        "backgroundColor": "#6a7985"
      }
    }
  },"dataset": {
    "source": [
      [
        null,"Gifts","In Kind","Pledges"

  },"xAxis": {
    "type": "category","axisLabel": {
      "rotate": 90
    }
  },"yAxis": [
    {
      "type": "value","axisLabel": {
        "formatter": "${value}"
      }
    }
  ],"series": [
    {
      "type": "line","areaStyle": {},"stack": "a"
    },{
      "type": "line","stack": "a"
    }
  ]
};

myChart.setOption(option);

<script src="//unpkg.com/echarts/dist/echarts.min.js"></script>
<script src="https://underscorejs.org/underscore.js"></script>
<div id="main" style="width: 600px;height:400px;"></div>

除此以外，我已经能够获得需要工作的所有其他图表类型。我想念什么？

解决方法

请勿将for (i in seq(from=0,to=100,by=20)){ var <- paste0('x',i) data <- mutate(data,!!var := ifelse(x >= i,1,0)) } x x0 x20 x40 x60 x80 x100 1 99.735037 1 1 1 1 1 0 2 9.075226 1 0 0 0 0 0 3 73.786282 1 1 1 1 0 0 4 89.744719 1 1 1 1 1 0 5 34.139207 1 1 0 0 0 0 6 88.138611 1 1 1 1 1 0 用作第一个维度的名称，而应使用诸如'date'之类的任意字符串：
