I am using latest version of Grafana.
I placed some general panels.
There are 3 panels in a row. But their margins are too large.
I want to make them more closely.
I can’t find any online instructions to follow, too.
Hi @corasphinxy,

We are excited that you joined our OSS community. Please read about some of the FAQs in the community 
Normally you can resize your panel in the Dashboard in a custom way you want simply by selecting its borders.
If that is not your case, then please share some screenshots so that we can have more information about it.
