Plotly Subplots的Specs参数错误

Question

我得到的值错误:

make_subplots的'specs'参数必须是一个2D的字典列表，其维度为(1 x 1)。收到的价值类型& lt;类"列表"祝辞:[[{secondary_y:假}],[{"secondary_y":真}],[{"colspan":1},没有]]

我指的是现有的帖子情节子情节问题与规格，值错误和遵循相同，但错误仍然存在。

下面是代码片段:

Answer 1

出现错误是因为规格的尺寸与子图中定义的行数和颜色不匹配。你有2行和1栏，这意味着你的规格必须是一个2x1形状的列表(即两个列表的列表)。下面是一个例子:

specs=[[{"secondary_y": True, "colspan": X, "rowspan": X, "b": 0.05, etc}] , 
[{"secondary_y": False}]]).

另外，请记住colspan可以接受的最大值是您为col参数定义的值。最后，如果需要为每个子情节传递更多设置，可以简单地将它们添加到相应的字典

中。
