Hi Brian,
cannot confirm that the choice is gone, I just checked with gretl 2025a. 
Please double-check, and if you still think it's not there anymore, 
please tell us as always: what version are you running, and ideally 
exactly what data / sample combination you are using.
cheers

 HI
 it would appear that the latest Gretl version post estimation in both 
 Arima and OLS Analysis Forecast no longer provides the shaded area 
 confidence interval option that was hitherto available. It is a much 
 preferable option to the confidence interval bars which is the only 
 mrthod and clutters up the graphical presentation which aesthetically 
 clutters up the graphical presentation. Indeed the Arima forecast 
 graphic provides the erro bar in the key, but doesn't even plot it. 
 Any chance of restoring the previous choice selection and functionality?

     Dear all,
     this message is to inform the community about the activity in our
     function package repository: during the month of December 2024, 3
     packages were updated to a new version:
     "graphlasso", by Sven Schreiber (graphical Lasso --- l1 shrinkage for
     covariance matrices)
     "lomackinlay", by Allin Cottrell and Sven Schreiber (Lo-MacKinlay
     variance ratio test for determining if a time series is a random walk
     process)
     "BACE", by Marcin Błażejowski and Jacek Kwiatkowski (Bayesian
     Averaging
     of Classical Estimates)
     I'll reserve a special mention for the "graphlasso", which now uses a
     new internal function to speed up computation.
     Sorry if this message comes relatively late in the month, but I
     was away ;)
     Download and enjoy!
