No graphical explain plan with pgadmin 3.6.5

[SQL Design <sql.design.company@xxxxxxxxx>]

Hello,

But if I do "explain select...", I have a textual explain plan.

In Preferences, all options for explain are set to true.

I installed PostgreSQL and pgadmin4 via Docker (last version) on Ubuntu 16.04.

Please have a look on https://sqldesign.blog/2018/12/24/how-to-install-pgadmin4-with-docker/

Everything else seems to work fine

Thank you for your attention
