高图表在xaxis中显示错误的月份值 [英] High chart Displaying wrong month value in xaxis

问题描述

问题描述：尝试在xAxis中显示月份年值，例如2016年1月至2016年12月。
我在 $ scope.chartxAxisData 对象中具有相同的值，但在 xAxis 格式化后显示此值时，它将从'2015年12月'开始显示至'2016年11月'

Issue Description: Trying to display month-year value in xAxis for example 'Jan 2016' to 'Dec 2016'. I have the same value in $scope.chartxAxisData object but when display this value after formatting in xAxis it start to display from 'Dec 2015' to 'Nov 2016'

//$scope.chartxAxisData Data as follow

//Value in  Time

    series: [{
        showInLegend: false,
        name: 'series',
        data: $scope.chartSeriesData
    }]
};

输出

它应该从 2016年1月开始。

推荐答案

您的时间超出了范围，因为您正面临时区问题，解析器可能会将长片解析为不同的时区，导致上个月的时间。您应该将此功能应用于图表。它是一个全局函数，用于设置所有图形的时区。

Your time is out of scope because you are facing timezone issues, the parser probably parses the longs to a different timezone, resulting into a time in the previous month. You should apply this function to your charts. It is a global function which sets the timezone for all your graphs.

Highcharts.setOptions({
    time: {
        timezone: 'Asia/Kolkata'
    }
});

或者，替换

时间：{useUTC ：false}

在你已经发布的highcharts代码中，在本地更改。

Or, replace the
time: { useUTC: false }
within your highcharts code you already posted with this, to change it locally.

此外，在为了实现这个目的，你还应该导入一些 moment.js 库。

Additionally, in order for this to work, you should also import some moment.js libraries.

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.13/moment-timezone-with-data-2012-2022.min.js"></script>
