Answer 1

In Power Query Editor , create a new table using this below code-

Please replace your_table_name in this below code with your original 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"

**Keeping Location in the result set"-

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"

Output will be as below-

Output with location -

Now you can create your Pie Chart using this new table and the final output will be as below-
