Open new spreadsheet in Calc, add small amount of data for bar or line chart. Add chart using wizard. Use all defaults. When complete, double click on the bar (or line), and select Insert Data Labels (The values now appear correctly next to the bar/line.) Save the file in xlsx format. Close file and reopen. The data labels are no longer there. Version 3.6.4.3 (Build ID: 2ef5aff)

Basic support for data label export (=saving) should be now implemented (commits 32edd34a2056f0eb and 1aadb8789bc9a58e17). It doesn't deal with some advanced label features (text formatting etc.) but for most common use cases, it should suffice
