ChartJS v2.9.4 - 通过图例隐藏数据集时可能出现故障

如何解决ChartJS v2.9.4 - 通过图例隐藏数据集时可能出现故障

我不熟悉使用任何图表生成库。在我开始这个项目时，v2.9.4 是 ChartJS 的最新版本。

我遇到了特别是一张图表的问题。这是一个混合折线图和堆积条形图，显示七个不同数据集的数据。问题是当点击图例中的第一个指标以隐藏该指标时，它会更改倒数第二个指标的值。

当图表首次加载时，3 年平均值值远高于应有的值。如果我单击 2020 Pickups 将其隐藏，2020 Pickups 会按原样消失，但是 3 Year Average 数据集会减少到正确的值应该在图表加载时出现。

通过迭代循环将查询对象的结果推送到数组中来加载每个指标的值。查看查看源代码表明 3 年平均值 的正确值正在加载到数组中。我有 2020 Pickups 的隐藏前和隐藏后的屏幕截图。

Top is before hiding 2020 Pickups; bottom is after.

不幸的是，我们的开发环境受到限制，所以我没有可以分享的网址。

这是一些代码。它非常广泛，所以为了简洁起见，我只限于相关的内容。 [编辑：重新排列变量的顺序，包括正确的查询名称]
