Timedomain functions don't appear after a re-measurement without fiddling.

To recreate:

On x1zotws0 run erik.vonreis/diagtest/swept_envelope.xml. Select a time domain graph and note the sine wave. Run again (perhaps with changing frequency points). Note that the graph disappears.

In Trace -> Graph: select away from Time Series and select back. Select a graph and the time series will once again appear.
