Dashed Line for Last Recorded Values in WorkSheet

What does it mean when you have a dashed line?

I have a signal in which actual results get recorded approximately ~ 4 hours.

For some reason, in the SEEQ WorkSheet, the last two recorded values show up as dashed lines instead of solid lines. The values before that are all solid lines.

Is there a particular reason the last two recorded values are dashed lines?

Hi Nate,

that means that the values are uncertain and might be able to change (e.g. by using compression on the historian). 

Example:

You may notice the sample at ~15:39 was removed by the historian:

Now the datapoint was written to the achive. Notice the value from above (~15:46) was also removed:

Hope this helps. 

Regards,

Thorsten
