这是我根据我的上一个问题找到的问题,可以在这里找到:link
在链接中有一个小提琴,现在我意识到如果我有3个日期:
12.12.12 12:12:12 // 2012年12月12日
12.12.12 11:12:12
12.12.12 10:12:12
这是相同的日期,但差异只是1小时,然后这个差异没有显示在图表上。
我只想在x轴上显示那些日期和小时,这实际上是数据的一部分,并且做了一些事情,所以如果事情发生在同一个日期,实际上可以在图表上看到1小时差异,所以情节不会彼此重叠。
可以以任何方式完成吗?
答案 0 :(得分:2)
创建x轴时,可以使用
指示刻度间隔.ticks(d3.time.hour, 1)
每1小时打一次。有关详细信息,请参阅scale.ticks()的文档。
这是工作代码
