I have this spreadsheet where the graph produces a missing data point.
Here’s a link to the spreadsheet, a screenshot of the weird result, and a screenshot of Help->About for LibreOffice.
The spreadsheet above is a stripped-down version of the one where I discovered the issue. Produced by creating a new spreadsheet, copy/pasting the data only from the original, and creating a new graph on the data. It’s all pretty straightforward.
LibreOffice details (same as what’s in the screenshot):
Version: 18.104.22.168 Build ID: 1:6.0.4~rc2-0ubuntu0.16.04.1
This should be obvious from the above, but:
