How to show only dimension changes

First step: bring your data into usable format by unpivoting

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8krMU9JRSoTjWJ1oJe/EklSoQBIYgwT9cxB8mFhIfi6QnQzHIDHfzOxUJEGIia45OcgmQlQ65uVhmpiaAuUjnONWlJiXjWFPeGoxqspYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, Jan = _t, Feb = _t, March = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"Jan", type text}, {"Feb", type text}, {"March", type text}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Name"}, "Attribute", "Value"),
    #"Replaced Value" = Table.ReplaceValue(#"Unpivoted Other Columns",each [Attribute],each "1-" & [Attribute] & "-24",Replacer.ReplaceValue,{"Attribute"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Replaced Value",{{"Attribute", type date}})
in
    #"Changed Type1"

Then you can use Power Query, or the Visual Calculations feature to highlight changes.

Either upgrade to a version that supports Visual Calculations, or implement the logic in Power Query.
