> > Hi,
> > 
> > We've been trying to run Fetest in the attempt of plotting the sine wave data on
> > the history page on the web server. However each time we've tried running a new
> > plot we have come across the error of 'no data' from the variables. In the
> > status page we are clearly obtaining data from the frontend and it is updating
> > the variable as expected in SLOW.
> > 
> > When setting up MIDAS we managed to produce a history plot from Fetest but are
> > unable to do so any longer. We did have a go at modifying the Fetest code but
> > created a backup before doing so and are now running the original backup.
> > 
> > What could be causing the Fetest data not to be showing in the history plot?
> 
> Is the logger running? (this application is handling the history data).
> If yes: Did you change the variable names? If yes: restart the logger.
