Answer 1

在Power Query 编辑器中，使用以下代码创建一个新表-

请用您原来的表格名称替换下面代码中的your_table_name。

let
    Source = your_table_name,
    #"Removed Other Columns" = Table.SelectColumns(Source,{"Helmet", "Goggels", "Shoes", "Gloves"}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Removed Other Columns", {}, "Attribute", "Value"),
    #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"}),
    #"Grouped Rows" = Table.Group(#"Removed Columns", {"Value"}, {{"Count", each Table.RowCount(_), Int64.Type}})
in
    #"Grouped Rows"

**在结果集中保留位置"-

let Source = your_table_name,
    #"Removed Other Columns" = Table.SelectColumns(Source,{"Location", "Helmet", "Goggels", "Shoes", "Gloves"}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Removed Other Columns", {"Location"}, "Attribute", "Value"),
    #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"}),
    #"Grouped Rows" = Table.Group(#"Removed Columns", {"Location", "Value"}, {{"Count", each Table.RowCount(_), Int64.Type}})
in
    #"Grouped Rows"

输出如下-

输出位置-

现在您可以使用这个新表格创建您的饼图，最终输出如下-
