[gradsusr] Plot wind using regression

[syairah atiqah atiq]

Hello everyone.
I do need help to plot wing using regression. Below are my script:
* For HIP* *******    'open E:\IMPORTANT\Desktop\Latest\hip\sie.-2.ctl'    'set t 1 6'    'a=sie'    'close 1'*    'open E:\IMPORTANT\Desktop\Latest\wind\hp.mjjw.-2.ctl'*   'set grid off'   'set grads off'*   'set lon 20 115'   'set lat -75 0'** For zonal wind* ==============   'define coeff1 = tregr(a,u,t=1,t=6)'   'define aavg = ave(a,t=1,t=6)'   'define mavg1 = ave(u,t=1,t=6)'*   'define reg1 = coeff1*(a-aavg)+mavg1'** For meridional wind* ===================   'define coeff2 = tregr(a,v,t=1,t=6)'   'define aavg = ave(a,t=1,t=6)'   'define mavg2 = ave(v,t=1,t=6)'*   'define reg2 = coeff1*(a-aavg)+mavg2'**  Anomalies plot* ===============   'set arrscl 0.6 6'   'set arrlab on'   'd skip(reg1,2,2);reg2'*   'set map 1 1 12'   'draw map'*   'printim C:\Users\atiqah\Desktop\reg.hp.uv.png white'  *
Thank you in advance
