Highcharts：显示缺少数据点的线图 [英] Highcharts: Displaying Linechart with missing datapoints

问题描述

我正在计算一年中每周的财产平均价值。我想在一个折线图中显示这些信息（x轴是一年的一周，y轴是平均值，不同的线代表不同的属性）。

但对于任何给定的财产，我不一定每年都有一个数据点。如果我没有这样的数据点，我希望我的行可以在我拥有的数据点之间插入。

其他人遇到类似的问题吗？

解决方案

Highcharts并没有真正实现插值。当然，如果你的系列有一个缺失点，它将画出相邻两个之间的界线......但它不是你想发布的计算值。这只是这两个相邻点之间的最短距离。我会预处理您的数据以填写缺失的点，然后用注意：值或可能是颜色计算这些点的计算结果： 值。示例：第二个值来自您的预处理：

  data：[{y：7.0}，
 {y：6.9，
注：'calculated'，
 color：'＃BF0B23'}，
 {y：9.5}]

I am calculating the average-value of properties for each week of the year. And I want to display these information in a line chart (x-Axis is the week of year, y-Axis the average value and the different lines represent different properties).

But for any given property I do not necessarily have a datapoint for each week of the year. If I do not have such a datapoint I want my line for this property to interpolate between the datapoints I have.

Anyone else run into a similiar issue?
解决方案
Highcharts does not really do interpolation. Sure, if your series has a missing point it will draw the line between the adjacent two...but it is not a calculated "value" that you would want to publish. It is just the shortest distance between those two adjacent points. I would pre-process your data to fill in the missing points and then label these points as calculated with either a Note: value or maybe a color: value. Example where the second value is coming from your pre-processing:
data: [{ y: 7.0},
        {y: 6.9,
         Note: 'calculated',
         color: '#BF0B23'},
        {y: 9.5}]
