Kibana Dashboard : Gathering a visualize by topic

Is there a way to ghather some visualizes by topic in dhashbord ?

Thank you for help.

I'm not quite sure what you mean, can you elaborate?

I have 8 visualises in my dashbord and 4 of them for tracking performance of Oracle Dababase DB, the others for tracking an application performance APP.

In the dashboard, I need to make two blocs of visualizes ( one for DB and other for APP )

You can move and resize each dashboard panel using the buttons in the top right corner of each panel. Are you looking for something more elaborate than that?
