Is it possible to create trend lines for all data series at the same time? It appears possible to create a trend line only for individual data series.
The Calc user guide says that if no data series is selected, then trend lines for all data series will be created. However, this does not appear to be possible. I would like to understand if this is a bug or if this was never intended to be a feature.
After looking into this with Bugzilla, I have found that it is no longer possible to create a trend line for all data series at once. It is now possible to create several trend lines for the same data series and this increases the complexity of supporting the option to create trend lines for all data series.
The option to create a trend line is therefore grayed out until a data series is selected.
Please mention also the reference to bug with the source of the information. Thanks!
