Question

我正在使用高图来绘制数据，而在某些数据系列中，没有数据点，如图像波纹管和jsFiddle示例。在我在github上记录一个问题之前，我想问你是否有一些我想念的东西，或者它确实是一个问题。

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>

<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

的Javascript

$(function () {
    $('#container').highcharts({
        chart: {
                type: 'line',
                animation: false
            },
            title: {
                text: "abc"
            },
            xAxis: {
                type: 'datetime',
                dateTimeLabelFormats: { // don't display the dummy year
                    month: '%e. %b',
                    year: '%b'
                }
            },
            yAxis: {
                title: {
                    text: 'Time [ms]'

                },
                labels: {
                    step: 1
                },
                tickInterval: 100,
                minRange: 400
                //range: 200
            },
            plotOptions: {
                line: {
                    dataLabels: {
                        enabled: true,

                    /*stacking: 'percent'*/

谢谢！

Answer 1

您必须深入了解marker series属性的文档才能找到enabled属性，并说：

已启用：布尔值

启用或禁用点标记。如果为null，则当数据> 0时隐藏标记。密集，并显示更广泛的数据点。默认为null。

所以我不知道他们如何确定数据是否密集，但如果您希望始终显示标记，则应将enabled属性设置为true。

Answer 2

updated Plunk

在highcharts APi中，可以选择启用标记link，

使用

var BookSchema = new Schema({
  _creator : {type: Schema.Types.ObjectId, ref: 'User'},
  title: String,
  subtitle: String,
  author: String,
  language: String,
  pages: Number,
  publisher: String,
  publishedDate: String,
  isbn10: String,
  isbn13: String, 
  description: String,
  dimensions: {
    height: String,
    width: String,
    thickness: String
  },
  category: String,
  rating: String,
  bookType: String,
  imageLinks: {
    extraLarge: String,
    large: String,
    medium: String,
    small: String,
    smallThumbnail: String,
    thumbnail: String,
    uploaded: String   
  },
  uploadedImageLink: String,
  supplierData: {
    mrp: Number,
    supplierPrice: Number,
    quantity: Number
  },
  pricing: {
    salesPrice: Number,
    deliveryCharge: Number
  },
  dateAdded: Date,
  isFeatured: Boolean,
  isBestseller: Boolean
});

用于启用系列中的标记

HighCharts在折线图上缺少数据点
