javascript - 当显示 10 个以上系列时，Highcharts 列会变薄

Question

我遇到了与 this one 非常相似的问题，但具有分类轴。 问题是，如果我在绘图上添加太多系列(超过 10 个系列)，即使有足够的空间，列也会变得太细并且几乎看不见。 当我有 12 个系列(11 个柱形 + 1 个折线)时，图表的外观如下: 当我有 11 或 10 个系列时，会出现相同的行为，但是当我将系列数量减少到 9 个(8 个条形 + 1 个折线)时，图表看起来绝对正常:

但是，当我尝试使用 jsfiddle 重新创建此错误时和相同的 highcharts 版本(5.0.8)，无论我使用多少个系列，我都会得到绝对正确的行为。

Answer 1

这是由 boost 模块引起的，更具体地说是由 boost.seriesThreshold 属性引起的。它告诉我们何时应该在全局范围内启动提升(请参阅来源， https://code.highcharts.com/modules/boost.src.js )。因此，它与版本无关，就在之前(直到 v5.0.12)seriesThreshold 属性默认设置为 10(现在为 50)。
