[ncl-talk] Error while handling multiple WRF output files

[swati shewale]

Hiii,
using ncrcat I have single file containing 24 time step (3hrly, 3 days).
Now I want to plot temperature variable (average for each day, spatial,
panel plot). I am unable to take out time step for 1st day (0:7) and then
do average of it...then second day (8:15) ...likewise for third day
(16:23). I wrote a script, in that it takes average over all time steps.
what changes should I make so that I can get average over specific time
step? attached herewith script.
summary of variable temperature is as follow.

Variable: X

  MemoryOrder :    XY
  description :    TEMP at 2 M
