hyper trend chart stopped displaying trends

[RWD2]

Have been using Lookout for 4 years. have an 8 day hyper trend chart. it quit displaying data on chart but is still displaying data in expression object. Other hpyer trend charts in the same process still display data. What can be wrong? How do I check the data in the data base to see if it is being stored?

Is the database on the same computer?

Any error in Lookout?

To see the data in MAX, launch "Measurement & Automation" from desktop, select My System->Historical Data, right click on Citadel 5 Universe(if you use Lookout 6.x), select New->Trace View, select the database, the trace to view, click Add and OK. On Display tab, you will see the trends.

If it's not there, the data is not logged to database.

I moved all the logged data files (109 MB) to a different folder and and the data is now being logged into the empty floder and being desplayed in hyper trend,. Why did this fix the problem? 4 data members were all that were effected and they are displayed on the same chart.
