Using this pipeline
| essql ...
| pointseries ...
| plot ...
I get this outout , when my SQL query returns no result, e.g. due to no observations within time range defined in the essql WHERE condion.
- What should I insert in my pipeline just to show nothing (empty space) instead of the sign inserted above?
- Instead of showing nothing is it possible to insert a message or an alternative image (showing a message)?
