Hello!
When using LO (v4.3 or 4.4) Calc and graphing data, the source format is auto-checked (when it was not previously on pre-existing spreadsheets using LO v4.2) on the Y-Axis. When this is unchecked and 1234.1 is selected, everything graphs properly on Y-Axis. When the spreadsheet is saved, closed, and then reopened, the Y-Axis defaults again to Source Format 1234.
This only occurs in LO v4.3 and 4.4 versions. When using LO 4.2 or previous, I don’t have that issue. Has something changed in the new versions that I need to change somewhere else, or is this a bug? I am using a 13" MBP retina on OSX 10.9.5
In advance, many thanks for your time!
