[gradsusr] Trend MAP help!

[Malcolm Tang]

Hi Andrew,
Yes I've set it as

"set t 1 last"

For your info, I tried this and a spatial map came out:

'set lon 0 360'
'set lat -90 -75'
'set mproj sps'
'set t 1 last'

'd prec'

'ltrend prec precl'

'd precl'

I'm not sure if it's the spatial trend map that I'm looking for though....

But since the time is set from 1 to last, I can observe that the map
actually changes from 1 to the last time step.

Any idea or suggestion?

Thanks.
Malcolm
