<p class=MsoNormal>Dear Madam,<br>
Thanks for your reply.<br>
In fact I sent my question yesterday to the GrADS user group, but didn't get
any reply so far.<br>
I still could not resolve it.<br>
<br>
I found that there is no keyword search option in the Grads Forum archive.
Could you please tell me if there is any such?<br>
<br>
The data file link is given below:<o:p></o:p></p>

<p class=MsoNormal>Please also see my yesterday's email. if you have any
further suggestion, I will highly appreciate.<br>
--------------------------------------------------------------<br>
<br>
I have a multi-year SST data. I want to get a time series monthly and annual
mean plot of this data<br>
in a specified region in the same figure, keeping same x-axis (time) and y-axis
(SST).<br>
<br>
Please see below the code I am having, I also attach the figure I am getting
out of it.<br>
The annual mean value is found to be constant for all the 25 years I
considered.<br>
Definitely some mistake I am making in the code, which I am not able to
identify.<br>
<br>
Can somebody please help me the correct way of doing it?<br>
<br>
