错误无限一个值 altair jupyter [-infinite,infinite]

如何解决错误无限一个值 altair jupyter [-infinite,infinite]

大家好，我在 altair 上创建图表时遇到问题。该图可以正常工作，唯一的缺点是当我要与之交互时，我会获得以下标签。 我想解决的另一件事是，我希望系统需要在机器人案例中做出反应，因此当我与第一个下拉列表交互时以及与第二个或两者交互时。所有这些问题都解决了，当且仅当我将“transform_filter((selection & selection1))”替换为“transform_filter((selection | selection1))”时才出现，但万一我做了这个替换并且我想要根据两个过滤器对元素进行过滤是行不通的。

Infinite extent for field "timestamp": [Infinity,-Infinity] 
Infinite extent for field "Y1": [Infinity,-Infinity]

input_dropdown = alt.binding_select(options=[[1,2,3,4,5],[4],[3],[1],[2],[5],[1,[3,4],3],[4,2],[2,[5,3]])
selection = alt.selection_single(fields=['FIELD1'],bind=input_dropdown,name='FIELD1: ')

#dropdown
input_dropdown1 = alt.binding_select(options=[['M13','M14','M15','M16'],['M14'],['M13'],['M16'],['M15']])
selection1 = alt.selection_single(fields=['FIELD2'],bind=input_dropdown1,name='FIELD2: ')
#shape
selection_Operation= alt.selection_multi(fields=['FIELD1:N'],bind='legend')
shape_Operation = alt.condition(selection_Operation,alt.Shape('FIELD1:N'),alt.value('lightgray'))

color = alt.condition(selection,alt.Color('FIELD2:N'),alt.value('lightgray'))

interaction1 = alt.selection_interval(bind='scales',on="[mousedown[event.altKey],mouseup] > mousemove",translate="[mousedown[event.altKey],mouseup] > mousemove!",zoom="wheel![event.altKey]"
)

interactionY = alt.selection_interval(bind='scales',encodings=['x'],on="[mousedown[event.shiftKey],translate="[mousedown[event.shiftKey],zoom="wheel![event.shiftKey]")

).add_selection(interaction1,interactionY,selection,selection1,selection_Operation).transform_filter((selection & selection1))
