折线图出现了一个奇怪的问题。
如果您查看下面的GIF,则会看到2条折线图。第一个有错误,第二个很好。
第一个图表的值总计为零。但是,该图表似乎在每个x轴点都有一个值。它不应该具有该高度,应该像第二个图表一样在图表底部保持平坦。
创建第一个图表的值(列表中的每个项目的值为0
)
[{"value":0,"date":"Mar 18, 12:00 AM"},{"value":0,"date":"Mar 18, 1:00 AM"},{"value":0,"date":"Mar 18, 2:00 AM"},{"value":0,"date":"Mar 18, 3:00 AM"},{"value":0,"date":"Mar 18, 4:00 AM"},{"value":0,"date":"Mar 18, 5:00 AM"},{"value":0,"date":"Mar 18, 6:00 AM"},{"value":0,"date":"Mar 18, 7:00 AM"},{"value":0,"date":"Mar 18, 8:00 AM"},{"value":0,"date":"Mar 18, 9:00 AM"},{"value":0,"date":"Mar 18, 10:00 AM"},{"value":0,"date":"Mar 18, 11:00 AM"},{"value":0,"date":"Mar 18, 12:00 PM"},{"value":0,"date":"Mar 18, 1:00 PM"},{"value":0,"date":"Mar 18, 2:00 PM"},{"value":0,"date":"Mar 18, 3:00 PM"},{"value":0,"date":"Mar 18, 4:00 PM"},{"value":0,"date":"Mar 18, 5:00 PM"},{"value":0,"date":"Mar 18, 6:00 PM"},{"value":0,"date":"Mar 18, 7:00 PM"},{"value":0,"date":"Mar 18, 8:00 PM"},{"value":0,"date":"Mar 18, 9:00 PM"},{"value":0,"date":"Mar 18, 10:00 PM"},{"value":0,"date":"Mar 18, 11:00 PM"}]
创建第二个图表的值(列表中除2个项目外的每个项目的值均为0
。其他2个项目使图表线向上移动):< / p>
[{"value":0,"date":"Feb 16"},{"value":0,"date":"Feb 17"},{"value":0,"date":"Feb 18"},{"value":0,"date":"Feb 19"},{"value":0,"date":"Feb 20"},{"value":0,"date":"Feb 21"},{"value":0,"date":"Feb 22"},{"value":0,"date":"Feb 23"},{"value":0,"date":"Feb 24"},{"value":0,"date":"Feb 25"},{"value":0,"date":"Feb 26"},{"value":0,"date":"Feb 27"},{"value":0,"date":"Feb 28"},{"value":0,"date":"Mar 1"},{"value":0,"date":"Mar 2"},{"value":0,"date":"Mar 3"},{"value":0,"date":"Mar 4"},{"value":0,"date":"Mar 5"},{"value":0,"date":"Mar 6"},{"value":0,"date":"Mar 7"},{"value":0,"date":"Mar 8"},{"value":0,"date":"Mar 9"},{"value":0,"date":"Mar 10"},{"value":0,"date":"Mar 11"},{"value":0,"date":"Mar 12"},{"value":0,"date":"Mar 13"},{"value":0,"date":"Mar 14"},{"value":0,"date":"Mar 15"},{"value":0,"date":"Mar 16"},{"value":200,"date":"Mar 17"},{"value":200,"date":"Mar 18"}]

代码库中四处浏览,尝试修改各种设置时找不到答案。
更新:
答案 0 :(得分:1)
问题可能是因为您的y-min等于y-max(0
),如果您在所有数据都位于yScaleMax
时提供了0
,那么它就可以工作
