Line chart points from columns

Here is one possible approach

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45Wci4tKks1MDBU0lEyNAATINIUxozVgSsxAgoZgcSNQYQJiLAAKogFAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Curve = _t, ValueA = _t, MeasureA = _t, ValueB = _t, MeasureB = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Curve", type text}, {"ValueA", Int64.Type}, {"MeasureA", Int64.Type}, {"ValueB", Int64.Type}, {"MeasureB", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "List", each {{[ValueA],[MeasureA]},{[ValueB],[MeasureB]}}),
    #"Removed Other Columns" = Table.SelectColumns(#"Added Custom",{"Curve", "List"}),
    #"Expanded List" = Table.ExpandListColumn(#"Removed Other Columns", "List"),
    #"Extracted Values" = Table.TransformColumns(#"Expanded List", {"List", each Text.Combine(List.Transform(_, Text.From), "#(tab)"), type text}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Extracted Values", "List", Splitter.SplitTextByDelimiter("#(tab)", QuoteStyle.Csv), {"x", "y"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"x", Int64.Type}, {"y", Int64.Type}})
in
    #"Changed Type1"

Hi crizbe ,

I think you can create a relationship between Plan table and Curve table by [Curve] column.

For reference: Create and manage relationships in Power BI Desktop

Then you can create a slicer by [Plan] column from Plan table. 

By default:

Select Plan001:

Select Plan002:
