It seems that there are either no submits for your subprojects or, the 
other extreme, you create a separate buildstamp for every single 
subproject submit. In the first case you get this
http://open.cdash.org/index.php?project=UV-CDAT,
in the second case you should avoid CTEST_START() (at least without 
APPEND) for your subproject submits on the CTest side.
Interesting enough, there are almost no (more) public dashboards at 
Kitware that use subprojects; the setup of which is rather difficult to 
figure out.
