堆疊柱狀圖數(shù)據(jù)顯示在內(nèi)部的話，會(huì)把返回值為0的也展示出來(lái)航罗，所以需要單獨(dú)處理下

顯示在柱子里

series: [
              {
                name: '待發(fā)貨',
                type: 'bar',
                stack: 'total',
                barWidth: '30%',
                label:{
                  normal:{
                    show:true,
                    position:'inside',// 顯示在柱子里
                    // 這里處理下
                    formatter: function(params) {
                      return params.value > 0 ? params.value : '';
                    }
                  }
                },
                data: data.map((item, did) => item.waitDeliveryGoldWeight),
              },
            ],

注意

因?yàn)檫@里x軸只有一列堆疊柱狀圖禀横，所以采用的是series.push這種方法，百度上查詢出來(lái)說(shuō)x軸只多列堆疊柱狀圖的話不能用此方法(待驗(yàn)證)
我這里的 預(yù)警值 是不包含在原有總計(jì)里面的粥血，所以在總計(jì)這里把每個(gè)返回值都給加起來(lái)了柏锄。
