如何将缺失数据的高图默认为0 [英] How to make highcharts default to 0 for missing data

问题描述

我有1分钟的时间间隔。我想在一个缺少点的图表中显示0。

我找到了xAxis.ordinal，并将其关闭，以显示时间序列的正确间隔。问题是，它直接在点之间划线，而不会为0丢失数据。

解决方案

- 处理数据，用 0 替换 null ：

  var withNulls = [null，12，23，45，3.44，null，0]; 
 var noNulls = withNulls.map（function（item）{
 return（item === null）？0：item; 
}）;

I have a time series at a 1 minute interval. I would like to display that in a chart with missing points as 0.

I've found xAxis.ordinal and turned that off which displays the time series properly spaced out. The issue is that it draws lines between the points directly without going to 0 for the missing data.

解决方案

One way is by pre-processing the data, replacing null with 0:

var withNulls = [null, 12, 23, 45, 3.44, null, 0];
var noNulls = withNulls.map(function (item) {
    return (item === null) ? 0 : item;
});
