[gradsusr] Problems plotting station time series on Open GrADS 2.2.1

[Daniele Gandini]

Good morning to everyone.

I have a problem on plotting station time series on
Open GrADS 2.2.1 while I successfully represent them on
Open GrADS 2.0.1

Scanning description file:  RETEA_PIEMO_20200808.ctl
Data file RETEA_PIEMO_%y4%m2%d2.dat is open as file 1
LON set to 0 360
LAT set to -90 90
LEV set to 500 500
Time values set: 2020:8:8:0 2020:8:8:0
E set to 1 1
ga-> set t 1 last
Time values set: 2020:8:8:0 2020:8:12:16
ga-> set lat 45
LAT set to 45 45
ga-> set lon 8
LON set to 8 8
ga-> d t2m(stid=90139)

With Open GrADS 2.0.1 the plot is okay, while on
Open GrADS 2.2.1 i get this error message:

ga-> d t2m(stid=90139)
Data Request Error: Invalid grid coordinates
  Varying dimension 1 decreases: 45 to 45
  Error ocurred getting variable 't2m'
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = t2m(stid=90139)

Any suggestion?

Thank you in advance.
