You want this option if you mostly use Timelion expressions from within the Timelion app and don't need to add Timelion charts to Kibana dashboards. You may also want this if you make use of references to other panels.
Need to add a chart to a Kibana dashboard? We can do that! This option will save your currently selected expression as a panel that can be added to Kibana dashboards as you would add anything else. Note, if you use references to other panels you will need to remove the refences by copying the referenced expression directly into the expression you are saving. Click a chart to select a different expression to save.
