Comment 14 for bug 258705

Thank you ign_christian for your feedback. Great (in a way) you could reproduce it too :)

Just some notes.
Searching "Sort by X Values" with keyId language gives this:
https://translations.documentfoundation.org/fr/translate/#search=CFYgL&sfields=source,target,notes
=> tp_ChartType.ui

http://opengrok.libreoffice.org/search?q=tp_ChartType.ui&project=core&defs=&refs=&path=&hist= gives:
- chart2/source/controller/dialogs/tp_PointGeometry.cxx
- chart2/source/controller/dialogs/tp_ChartType.cxx
From the second one, searching "sort" keyword gives mpCB_XValueSorting, itself linked to "bSortByXValues" member of ChartTypeParameter, see http://opengrok.libreoffice.org/xref/core/chart2/source/controller/dialogs/ChartTypeDialogController.hxx#81
