</div>Your data is 3 hourly - this means that you can only have 8 time steps in<br>
a day and not 24 timesteps. You can try the following which gives you the<br>
plot (time series) of one day.<br>
<br>
'set t 1 8' * 8 timesteps = 1 day given your 3hourly data<br>
'set lon 60'<br>
'set lat 40'<br>
'd var'<br>

<br>
</div>Not sure what you mean by writing a ctl file. You dont need to write a ctl<br>
file to plot in GrADS.<br>
<br>
'set lon 60 100'<br>
'set lat 20 40'<br>
<br>
'd ave(variable,t=1,t=8)' * this is for day 1<br>
'printim day1.png white'<br>
<br>
'd ave(variable,t=9,t=16)' * this is for day 2<br>
'printim day2.png white'<br>
