Writing a positive signal ( + ) for temperatures

[Fernando Reis]

Hello folks,

I'd like to produce a chart with temperature and wind.  When Grads plots Negative temperatures it came with negative signal eg ( -78) and when the temperature is positive it came without signal.

I'd like to do it in a different way bye plotting positive values with a signal ( + 10 ) and negatives without it. ( 78 ).

Is that possible?

Thanks
