The plots are working now. I was on Qt 4.8.1 and Qwt 5.2.2, the defaults installed by the build-gnuradio script. I removed Qwt 5.2.2 (packages: libqwt5-qt4 libqwt5-qt4-dev) and installed Qwt 6.0.0 (packages: libqwt libqwt-dev). Perhaps it's worth changing these in the Ubuntu 13.* section of build-gnuradio.

I've noticed display problems on the time raster plots for Qwt less than version 6. So if you can install and use Qwt 6 (which should be pretty easy on Ubuntu 13.04), give that a shot.
