我正在X轴上创建具有时间DateTime值的高图散点图,并且在Y轴上创建了浮点值。问题是当我使用标签格式化程序将历元时间值转换为可读时间值(“DD-MMM-YYYY”)时,在X轴上创建了具有相同标题的多个标签,并且这些点不与X轴上的刻度线。HighCharts在X轴上的日期时间散点图不正确地绘制值

我为它创建了一个JSFiddle(Link)。我能做些什么来解决这个问题...

当你说 '点不与x轴标签匹配' 你的意思是(一)有一个特定的错误(例如错误日期/时间上的点),或者你的意思是(b)这些点不能与刻度线垂直对齐? – dcorking

(b)点不垂直对齐刻度线... –

TL:DR

让你的X轴的刻度线落在午夜tickInterval: (24 * 3600 * 1000)

详细的解答

您说过您看到“在X轴上创建了具有相同标题的多个标签”。然而,当我在最近版本的谷歌浏览器的查看您的小提琴,x轴看起来干净,虽然刻度线不与天完全一致:

screenshot from jsfiddle

我建议你尝试不同的浏览器,看看如果您的问题是由特定浏览器版本引起的。

您在评论中说过,如果您在较大的窗口中最大化图表,则会重复一些日期标签。

我建议你做一个更简单的阴谋来试图确定你的问题。

更新

如果你改变你的格式化功能,包括时间和日期:

Highcharts.dateFormat('%d-%b-%y %H:%M', moment.unix(this.value)) 

每对勾标记都会有不同的标签,即使它们落在同一天:

time format on axis labels

可替换地,定制的布局剔标记,以便他们总是在午夜时分。

更新2

我做了一个简单的演示,以显示刻度线和数据都与午夜对齐。最重要的特点是:

tickInterval: (24 * 3600 * 1000) // the number of milliseconds in a day. 

和:

[Date.UTC(2015, 11, 01), 75], // pure JavaScript to return a unix time (in milliseconds since unix epoch) of midnight on the 1st of December

如果您最大化图表,您将看到具有相同标题的多个标签http://jsfiddle.net/0ak0suf1/embedded/result/ –

是:即因为刻度线在同一天落下。刻度线间隔均匀,并自动添加,所以如果显示器足够大,有些会在同一天落下。 – dcorking

@NitinAgarwal我用几种不同的方式发布了一些代码来改善你的情况。我还从标签格式化程序中删除了一些无法访问的代码。 – dcorking
