How can I prevent NULLs from appearing in my HyperTrend graph when restarting DSC engine?

I am continuously logging data to a citadel database using DSC 7.0. Occasionally I need to restart the DSC engine because of a computer reboot, changes to SCF file, etc. Whenever I do this, and then review the data in HDV or with a HyperTrend graph in LV, there is a discontinuity in the traces during the time the DSC engine was not running. Using the cursors, you can see the value during this time is NULL. Generally this is desirable behavior since it indicates that no data was collected during this time period. However, I would like to know if there's setting to just "connect the points" instead of having a NULL in between. The reason is that some memory tags are updated very
infrequently, so the discontinuity appears much longer than just the time the DSC engine was not running. I want to connect the line to make the graph look nicer.
