Create matrix table

[SanderBI]

I'm trying to create a matrix table to work with in my report e.a. in my charts. 

See below's example. On the left my current table and on the right the result I want. I've tried a few things in the query editor and using DAX. However, I did not get the result I want. I know I can create such a table easely in my report but then I cannot use is in other visuals.

The categories are dynamic so I cannot hard code these columns names. 

Can someone help me out?

Hi @SanderBI ,

As @Anonymous , we can pivot your table in power query. Here I create one sample for your reference. M code  as below.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ31DcyMLRQ0lFyBGJDpVgdFEEnIDZCF3QGYmOooBGydhN0QZB2U3RBkHYzpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Dates = _t, Categories = _t, Values = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Dates", type date}, {"Categories", type text}, {"Values", Int64.Type}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Categories]), "Categories", "Values", List.Sum)
in
    #"Pivoted Column"

Pbix as attached.

@SanderBI,

You can pivot your table in query editor to get the desired result.
