即使聚合函数是非汇总函数,也会创建堆积条形图
Stacked bar chart is created even though aggregation function is non-summative
我有一个串联图,它有一个主线图,主线图有一个画笔选择工具,允许用户平移线和点并更改其他 4 个图上的数据。对于其他图表之一,我试图取折线图数据的平均值,但它不起作用。我没有给我一个单一的条形图,而是得到了堆叠条形图和错误:“即使聚合函数是非求和的(“均值”)也应用了堆叠”。
这是我的代码:

第一个图是折线图,第二个图是聚合失败的图,我得到了堆栈。Here is an image of what the graph looks like currently。任何帮助将不胜感激。
Vega-Lite 的编码聚合将按您在一组编码中指定的未聚合字段隐式分组。第二个图表编码的简化版本如下所示:
{
"encoding": {
"color": {"field": "Total"},
"y": {"field": "Total", "aggregate": "average"},
"x": {"field": "Species"},
"tooltip": [
{"field": "Species"},
{"field": "Total", "aggregate": "average"},
{"field": "Variable"}
]
未聚合的编码是 ["Total", "Species", "Variable"]
,因此在计算每个组内 Total
的 average
之前,操作将 group-by 这些。在每组中取 Total
的平均值之前按 Total
的唯一值分组可能不是您所希望的。
也许从该图表中删除颜色编码会给您带来更有意义的结果。
