X軸上帶有日期時間的HighCharts散點圖無法正確繪制值

Question

我正在用X軸上的歷時DateTime值和Y軸上的浮點值創建高圖散點圖。 問題是當我使用標簽格式化程序將紀元時間值轉換為可讀時間值（“ DD-MMM-YYYY”）時，在X軸上創建了多個具有相同標題的標簽，並且這些點與X軸上的刻度線。

我已經為此創建了一個JSFiddle（ Link ）。 我該怎么做才能解決這個問題...

$(function () {
$('#container').highcharts({
    chart: {
        type: 'scatter',
        zoomType: 'xy'

        text: 'Errors'
    },
    subtitle: {

    },
    xAxis: {
                allowDecimals: false,
                title: {
                    text: 'days',
                    scalable: false
                },
                type: 'datetime',
                labels: {
                    formatter: function () {
                            return Highcharts.dateFormat('%d-%b-%y', moment.unix(this.value));

Answer 1

TL：DR

使您的x軸刻度線通過tickInterval: (24 * 3600 * 1000)在午夜tickInterval: (24 * 3600 * 1000)

詳細答案

您說您看到了“在X軸上創建了具有相同標題的多個標簽”。 但是，當我在最新版本的Google Chrome瀏覽器中查看您的小提琴時，x軸看起來很干凈，盡管刻度線與日期並不完全一致：

我建議您嘗試使用其他瀏覽器，以查看您的問題是否由特定的瀏覽器版本引起。

您在評論中說，如果您在更大的窗口中最大化圖表，則會重復某些日期標簽。

我建議您做一個簡單的圖來嘗試確定您的問題。

更新

如果更改格式化程序功能以包括時間和日期：

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

每個刻度標記將具有不同的標簽，即使它們落在同一天：

或者，自定義刻度線的布局，使它們始終位於午夜。

更新2

我做了一個簡化的演示，以顯示與午夜一致的刻度線和數據。 重要功能包括：

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

 $(function() { $('#container').highcharts({ chart: { type: 'scatter', zoomType: 'xy' }, title: { text: 'Datetime scatter plot demo' }, subtitle: { text: 'for Stack Overflow' }, xAxis: { tickInterval: (24 * 3600 * 1000), // the number of milliseconds in a day allowDecimals: false, title: { text: 'Date', scalable: false }, type: 'datetime', labels: { formatter: function() { return Highcharts.dateFormat('%d-%b-%y', (this.value)); } } }, yAxis: { title: { text: 'Value' } }, series: [{ "name": "Demo values", "data": [ [Date.UTC(2015, 11, 01), 75], [Date.UTC(2015, 11, 02), 70], [Date.UTC(2015, 11, 02), 80], [Date.UTC(2015, 11, 02), 45], [Date.UTC(2015, 11, 03), 65], [Date.UTC(2015, 11, 03), 40], [Date.UTC(2015, 11, 05), 75] ] }], }); });
