The Help page is written and can be source for extended tips in the sparkline dialog https://help.libreoffice.org/master/en-US/text/scalc/01/sparklines.html?DbPAR=CALC#bm_id901654173679276 File to touch: sparklinedialog.ui 1) Use Glade to open sparklinedialog.ui 2) Open "Accessible Description" dialog of the accessible tab of each relevant dialog widget, 3) In "Context for translation" add "sparklinedialog|extended_tip|<dialog_widget>, where <dialog_widget> is the relevant selected widget to add E.T. 4) in "Text" add the extended tip text. Do not use %PRODUCTNAME here, use "Calc" or "application" (https://bugs.documentfoundation.org/show_bug.cgi?id=142704#c10)

Two notes: 1. To find the "accessibility" tab, one may have to scroll the top right side tab bar of the Glade to find the 🚹 (man) icon. Then a click on 🖉 (pencil) icon to see "Context for translation" and other options. 2. One may need a recent version of Glade to be able to do this task. Try opening the sc/uiconfig/scalc/ui/xmlsourcedialog.ui file and finding "mlsourcedialog|extended_tip|XMLSourceDialog" as an example. I was using Glade 3.22.2 in Ubuntu 20.04, and the "Context for translation" field was completely empty. Using Glade 3.38.2 in Ubuntu 22.04, "xmlsourcedialog|extended_tip|XMLSourceDialog" is visible in that place.
