Hello, Walt Unfortunately, I can't think of a way to do that.
You could simulate it by iterating over 24 hours, then taking the difference from the value of the previous hour. Something like (NOT TESTED): #set $prevValue = None #for $hour in $day.hours Current value = $hour.outTemp #slurp # if $prevValue is not None Difference from previous value = $($hour.outTemp - $prevValue) # else N/A # end if #set $prevValue = $hour.outTemp #end for See the Cheetah User's Guide <http://cheetahtemplate.org/users_guide/output.html> for nuances on the Cheetah template library (such as the #slurp directive above). -tk On Mon, Mar 19, 2018 at 8:48 AM, Walter Smith <[email protected]> wrote: > Hi I am new, I searched previous posts and didn't see an answer for this. > > I want to modify a report template to show the hourly readings for the > last 24 hours.
