I have constructed phylogenetic tree by Bayesian inference method using BEAST software and analysis the tree using Fig Tree. But I didn't find, how to display the Likelihood vale using Fig Tree on phylogenetic tree?
If you mean node support (either from bootstraping or posterior probabilities) you can select this from the options on the left (e.g. Branch Labels -> Display -> Posterior (or label)).
If you are interested in the likelihood of the tree as a whole (either maximum likelihood or Bayesian), this depends on the software used to generate the tree. Usually at the end of a run the software displays the likelihood.
For trees generated with BEAST you can see the likelihood with a software called TRACER (https://beast.community/tracer) in which you can open the .log files.
If you have saved your tree with branch length estimates, then the BS or PPs values should show up if you check the branch label option. A drag down menu will allow you to click on BS or PP or simply label to show these values on the tree branches.
