X 轴中的最后一个标签，日期时间格式不在高图表中
last label in x axis with datetime format not coming in highchart
我用高图来绘制图表。其中 x 轴有日期时间，y 轴有数字。但问题是 X 轴上的最后一个标签不会到来。所以如果你能帮忙，请帮我做。
如果我使用 Endontick 并显示最后一个标签，它会在末尾添加 00：00：04这是相同代码的jsfiddle的链接就像一个4k行代码https://goo.gl/bbwZRC

不要使用类别。在您的情况下：
-
将
xAxis.type设置为datetime（不是type: 'time'！删除类别，或至少将categories替换为tickPositions. -
如果点之间的间隔固定，请使用
series.pointStart和series.pointInterval（或pointIntervalUnit）。如果您的数据可能不规则，请更改您的数据格式。目前您有data: [value, value, value].而是使用data: [ [timestamp, value], [timestamp, value], [timestamp, value] ] -
添加
xAxis.tickInterval选项 - 例如3600 * 1000，以确定刻度应该出现的位置。 -
添加
xAxis.maxPadding = 0选项 - 因此最后一个即时报价不会超过极端值。
就这样。点之间有固定间隔的示例：https://jsfiddle.net/txuhs36t/2/
