Convert start and end dates to continuous range

I have the following table: What is the best way to turn the Start and End columns into a date continuum so that you can easily graph the consumption and amounts per day? Greetings a...

    Hi Syndicate_Admin ,

    According to your description, I create a sample.

    Here's my solution.

    1.Create a Date table, don't make relationship between the two tables.

    Date = CALENDARAUTO()

    2.Create two measures.

    Consumption Measure =
MAXX (
    FILTER (
        'Table',
        MAX ( 'Date'[Date] ) >= 'Table'[Start]
            && MAX ( 'Date'[Date] ) <= 'Table'[End]
    ),
    'Table'[Consumption]
)

    Importe Measure =
MAXX (
    FILTER (
        'Table',
        MAX ( 'Date'[Date] ) >= 'Table'[Start]
            && MAX ( 'Date'[Date] ) <= 'Table'[End]
    ),
    'Table'[Importe]
)

    Put Date from Date table in X-axis, Concept in Legend and measure in Y-axis, get the result.

    I attach my sample below for your reference.

This is sample M Script that generates dates using Start and End Dates columns.

let
  Source = Table.FromRows(
    Json.Document(
      Binary.Decompress(
        Binary.FromText(
          "dZBBDoAgDAT/wtnEdhHavsX4/29IBJM14I2SSTu755m07qI7BJq21F6Cd6iWrq0BwYAzgA5kAuA0lOgAGGDa8wNA6U+FTtjCITNdSgcOlsy0wccG+5O0Om9AWZzgosBC7nMKOcghtG9g4EM7FgAbu8wpPj34qNr/JKssmhSOOSQ5OjizxaIHHqL1cN0=",
          BinaryEncoding.Base64
        ),
        Compression.Deflate
      )
    ),
    let
      _t = ((type nullable text) meta [Serialized.Text = true])
    in
      type table [Start = _t, End = _t, Value = _t]
  ),
  #"Changed Type" = Table.TransformColumnTypes(
    Source,
    {{"Start", type date}, {"End", type date}, {"Value", Int64.Type}}
  ),
  #"Added Custom" = Table.AddColumn(
    #"Changed Type",
    "Number of Days",
    each Duration.Days([End] - [Start]) + 1,
    Int64.Type
  ),
  #"Added Custom1" = Table.AddColumn(
    #"Added Custom",
    "Dates",
    each List.Dates([Start], [Number of Days], #duration(1, 0, 0, 0)),
    type list
  ),
  #"Expanded Dates" = Table.ExpandListColumn(#"Added Custom1", "Dates"),
  #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Dates", {{"Dates", type date}}),
  #"Added Custom2" = Table.AddColumn(
    #"Changed Type1",
    "New Value",
    each [Value] / [Number of Days],
    type number
  ),
  #"Removed Other Columns" = Table.SelectColumns(
    #"Added Custom2",
    {"Start", "End", "Dates", "New Value"}
  )
in
  #"Removed Other Columns"

I understand that the only way to process this is in the consultation phase, with Power Query; No chance with DAX?
