以固定间隔在x轴上渲染Highcharts数据时间 [英] rendering Highcharts datatimes on the x axis at regular intervals

问题描述

我有两个充满数据的数组。一个数组只是随机整数（例如1.7,2.8,3.4等），另一个数组是该数据的相应时间戳的对应列表（例如1366585199）。

I have two arrays full of data. One array is just random integers (e.g. 1.7, 2.8, 3.4, etc.) and the other array is a corresponding list of unix timestamps for that data, (e.g. 1366585199).

目前，我的Highcharts代码看起来像这样：

At the moment my Highcharts code looks a little something like this:

dataArray = ("2.4","5.6","3.1", ...);
timeArray = ("1366585199","1366585233","1366585355", ...)

       function foo(dataArray, timeArray) {
            $('#viz_1').highcharts({
                chart: {
                    type: 'line'
                },
                title: {
                    text: 'Data Index'
                },
                xAxis: {
                    type: 'datetime', // this isn't doing anything??
                    categories: timeArray
                },
                yAxis: {
                    title: {
                    text: 'Data Value'
                    },
                },
                series: [{
                    name: topicID,
                    data: JSON.parse("[" + dataArray + "]")
                }]
            })
        }; 

这适用于向页面呈现折线图，但X轴明显充满了大约50个Unix时间戳！

This works and renders a line graph to the page but the X Axis is obviously full of about 50 Unix timestamps!

我似乎无法弄清楚如何让Highcharts API获取Unix时间戳数组，用它来排列数据点，但只显示一个X轴上的人类可读日期是否定期？

I can't seem to figure out how to get the Highcharts API to take the array of Unix timestamps, use it to line up the data points, but only show a human-readable date on the X axis at regular intervals?

推荐答案

你不能混合'datetime'和类别。
我倾向于将x / y值作为成对发送到HighCharts。喜欢：

You cannot mix 'datetime' and categories. It is my preference to send in the x/y values as pairs into HighCharts. Like:

data: [
            [Date.parse('01/01/2000 00:00:00'), 55205],
            [Date.parse('01/01/2003 00:00:00'), 59091],
            [Date.parse('01/01/2004 00:00:00'), 64347],
            [Date.parse('01/01/2005 00:00:00'), 71067],
            [Date.parse('01/01/2006 00:00:00'), 77770],
            [Date.parse('01/01/2011 00:00:00'), 81166]
        ]

如果您有javascript时间戳，您也可以发送以下内容：

If you have javascript timestamps you can send those in as well like:

[31536000000, 456]
