給chart添加click事件

var toggle = false
myChart.on('click', chartClick)

//點擊柱狀圖
function chartClick(param) {
    if (param.name == '總費用' && !toggle) {
        option.series[1]['data'] = [arr[0]] //只顯示第一條數(shù)據(jù)
        toggle = !toggle
    } else if (param.name == '總費用' && toggle) {
        option.series[1]['data'] = arr //再次點擊顯示所有
         toggle = !toggle
    }
    myChart.setOption(option)
}
