Option do not summarize area chart

Hi  AyaneYep , 

If you don't want to summarize, I think you need to create an index column like below

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUTJUitWBsIzgLBMwKwnIMoWzjOEsiLpkuN5kuDooKxYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [name = _t, amount = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"name", type text}, {"amount", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"name"}, {{"all", each _, type table [name=text, amount=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each Table.AddIndexColumn([all], "index",1,1)),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"all"}),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Removed Columns", "Custom", {"amount", "index"}, {"amount", "index"})
in
    #"Expanded Custom"

Then design chart like below
