我是 Power BI 的初学者。我正在尝试为每个国家/地区创建一个包含摩天大楼数量的列，但不知道该怎么做。

如果你想在 M 中做到这一点，这很容易。只需按国家分组：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Position = _t, #"Building Name" = _t, Meters = _t, Floors = _t, Completed = _t, City = _t, Country = _t]),

创建一个计算度量来使用 DAX 计算摩天大楼的数量：

=COUNTA([建筑物名称])

然后在报表上，将 Country 和新度量拖放到图表中。
