I have an easy chart that has been trending power usage. It has been operational for a long time and now it is no longer displaying the trend. The value of the tag is good and everything else looks good as far as history being checked. It is not just my profile either.  
Thanks in advance for the help.

What version of Ignition are you running? Also, have you tried dropping an Ignition table component on a window and then dragging the dag in question onto the table? You should see a list of history data with different overlays depending on whether or not the tag is believed to have good or bad quality at the time of the history being recorded.
