用echarts 繪制柱狀圖出現(xiàn)問(wèn)題

用echarts繪制柱狀圖，配置項(xiàng)如下：

{"title":{"text":"用量統(tǒng)計(jì)圖","textStyle":{"fontWeight":400,"fontSize":14}},"legend":{"data":["全部","音頻","標(biāo)清視頻","高清視頻","超清視頻"],"y":"bottom","tooltip":{"show":true}},"color":["#2c80ff","#000","#e2431e","#00FF00","#737EF4"],"toolbox":{"right":40,"feature":{"magicType":{"type":["bar","line"]},"saveAsImage":{"name":"usage"},"restore":{}}},"tooltip":{"trigger":"axis"},"xAxis":{"type":"category","data":["2018-08-10","2018-08-11","2018-08-12","2018-08-13","2018-08-14","2018-08-15","2018-08-16"]},"yAxis":{"type":"value","scale":true,"splitLine":{"show":true}},"graphic":[{"type":"line"},{"type":"ring"}],"series":[{"name":"全部","type":"bar","data":[[0,18227],[1,0],[2,0],[3,1927],[4,18304],[5,35167],[6,1210]]},{"name":"音頻","type":"bar","data":[[0,0],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0]]},{"name":"標(biāo)清視頻","type":"bar","data":[[0,18227],[1,0],[2,0],[3,1927],[4,18304],[5,35167],[6,1210]]},{"name":"高清視頻","type":"bar","data":[[0,0],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0]]},{"name":"超清視頻","type":"bar","data":[[0,0],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0]]}]}

繪制出的圖表如下：

配置項(xiàng)放于react的state中，修改state中的echarts配置項(xiàng)

修改后的配置項(xiàng)如下：

{"title":{"text":"用量統(tǒng)計(jì)圖","textStyle":{"fontWeight":400,"fontSize":14}},"legend":{"data":["次數(shù)"],"y":"bottom","tooltip":{"show":true}},"color":["#2c80ff"],"toolbox":{"right":40,"feature":{"magicType":{"type":["bar","line"]},"saveAsImage":{"name":"usage"},"restore":{}}},"tooltip":{"trigger":"axis"},"xAxis":{"type":"category","data":["2018-08-10","2018-08-11","2018-08-12","2018-08-13","2018-08-14","2018-08-15","2018-08-16"]},"yAxis":{"type":"value","scale":true,"splitLine":{"show":true}},"graphic":[{"type":"line"},{"type":"ring"}],"series":[{"name":"次數(shù)","type":"bar","data":[[0,0],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0]]}]}

修改后的數(shù)據(jù)data的y軸坐標(biāo)皆為0，但是繪制的柱狀圖卻如下：

在echarts提供的校驗(yàn)網(wǎng)站中http://gallery.echartsjs.com/...，如下：

這個(gè)問(wèn)題有哪位同學(xué)遇到過(guò)么？原因是由于圖例組件的標(biāo)記（legend）不可以修改么？麻煩知道的同學(xué)幫忙指導(dǎo)一下，感謝！
