Bar chart in Power BI

Hello together,

 

I have a question. I would like to draw a bar chart in Power BI which counts the values of the same type for two classes.

The table looks like this:

Class 1Class 2
01
11
11
01
10

 

I would like to receive the following bar chart:

 

 

How can I implement this in Power BI? Thanks a lot for your help!

You need to transform your table in Power Query:

Go to Power Query > Get Data > Blank Query > go to Advanced Editor in View Menu, Clear all that is there and paste the below code.

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlDSUTJUitWJBpKYLFRZA6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Class 1" = _t, #"Class 2" = _t]),
    #"Added Index" = Table.AddIndexColumn(Source, "Index", 1, 1, Int64.Type),
    #"Changed Type" = Table.TransformColumnTypes(#"Added Index",{{"Class 1", Int64.Type}, {"Class 2", Int64.Type}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Index"}, "Attribute", "Value"),
    #"Duplicated Column" = Table.DuplicateColumn(#"Unpivoted Other Columns", "Value", "Value - Copy"),
    #"Removed Columns" = Table.RemoveColumns(#"Duplicated Column",{"Index"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Value", "Legend"}, {"Attribute", "Class"}, {"Value - Copy", "Value"}})
in
    #"Renamed Columns"
