Superset项目柱状图来自Echarts

首先Echarts实现柱状图数据缩放初始化默认值的效果

核心代码 

设置Datazoom 的start 和end

myChart.showLoading();
$.get(
  ROOT_PATH + '/data/asset/data/obama_budget_proposal_2012.list.json',
  function (obama_budget_2012) {
    myChart.hideLoading();
    option = {
      tooltip: {
        trigger: 'axis',
        axisPointer: {
          type: 'shadow',
          label: {
            show: true
          }
        }
      },
      toolbox: {
        show: true,
        feature: {
          mark: { show: true },
          dataView: { show: true, readOnly: false },
          magicType: { show: true, type: ['line', 'bar'] },
          restore: { show: true },
          saveAsImage: { show: true }
        }
      },
      calculable: true,
      legend: {
        data: ['Growth', 'Budget 2011', 'Budget 2012'],
        itemGap: 5
      },
      grid: {
        top: '12%',
        left:
