bug report - libreoffice - calc - xyplot with individual dot descriptions

[Michael Schumann <michael.schumann.123@xxxxxx>]

    Hello all,
    
    I hope I'm doing this the right way.
    I "just" want to file a bug report.
    
    The bugreport-website
    (https://wiki.documentfoundation.org/QA/BugReport) refers to this
    mailing-list website
    (https://wiki.documentfoundation.org/Development/Mailing_List), 
    but the mailing-list website states "Do not mail to the list for:
    Reporting bugs ...    Reporting bugs is explained here: BugReport"
    and refers back to the bugreport-website.
    
    I've first put the topic for discussion on the German LibreOffice
    forum
    (https://www.libreoffice-forum.de/viewtopic.php?f=6&t=40478),
    and the received feedback / recommendation was to place a bugreport.
    At the link, you can also find a example file for illustrating the
    problem.
    Since I'm using the German localized version, please don't get
    offended if my translation to English is a bit lopsided.
    
    
    
    1) My system
    
    Ubuntu LTS24.04
    Libre Office - Calc - Version 24.2.7.2 (X86_64)
    localization: German
    
    
    2) What I want to achieve
    
    Having a diagram plotting several (more than one) datalines.
    Each dataline ist a list of several datasets (x-values, y-values,
    description).
    The diagram should show for each dataline and each dataset (aka each
    x/y-point) the corresponding description.
    
    
    3) What I've done - step by step
    
    enter the data to the cells in the calc sheet: e.g. data for four
    datalines

    create a diagram (a plot?) of the type x/y-scatter subtype
    dots-connected-with-lines

    at data source, pressing the "add" button four times to create 4
    datalines
    for each of these 4 data lines:
      select the button dataline/name and fill the field with the
    cell-index of the cell containing the dataline-name, using the
    select-by-mouse button
      select the button dataline/x-values and fill the field with the
    cell-indices of the cells containing the list of x-values, using the
    select-by-mouse button
      select the button dataline/y-values and fill the field with the
    cell-indices of the cells containing the list of y-values, using the
    select-by-mouse button
      fill the field called "data-description" with the cell-indices of
    the cells containing the list of descriptions, using the
    select-by-mouse button

    What I noticed:
    Each dataline has its individual name, x-values, y-values
    But the data-description applies to all datalines together, it is
    NOT individual for each dataline.
    If I e.g. enter cell-indices data to the data-description field for
    dataline 2, it is applied to all four data lines.
    
    At the diagram by selecting (right mouse clicking) each of the 4
    displayed data lines:
     enable the show-description option
     mouse rightclicking one of the shown descriptions (numbers)
     select button "edit data description" and sub-button "data
    description"
     default enabled is the option "value as number"
     disable this option
     enable the "category"  option
    
    result:

    only one of the four datalines can get the correct dot descriptions,
    all other datalines just show the same descriptions which are wrong
    for them
    
    
    4) my opinion
    
    IMHO, the data-description field should be individual for each data
    line,
    so that different datalines can have different descriptions.
    
    
    
    With Best Regards,
