? Which version was that ?
Only an old version of xgraph-12.1 will work with 20.04 !
I.e. the (Ubuntu 14.04) xgraph_12.1-17_amd64.deb

"xgraph_12.1-17_amd64.deb" was tested OK 'May 03' on a rather new install of Ubuntu 20.04 :
Code:
cd ns-allinone-2.35/xgraph-12.2/examples/
xgraph xgtest.xg
You will of course have to uninstall / remove / delete the alien xgraph_4.38
