If X server is running on the target host and you want the program to display there, you usually perform 'export DISPLAY=:0' where :0 would mean the first X server running. If you are running several X servers (for example Xvnc) on the target host, :0 may become :1 or another number, depending on X server configuration.
If you have X server running locally (the machine you are connecting from) you could use 'ssh -X ...' or 'ssh -Y' to log in to the host and forward your display to the program run remotely. See other answers on redirecting X server over SSH.
Edit: Please check the answer in the linked article.
TL;DR:
- Ensure xauth is installed on target
- In /etc/sshd_config set
X11Forwarding yes
- Run ssh with -vv to check what is the problem, if any
