[gradsusr] [EXTERNAL] [BULK] How to display the output number value of a variable on the Graph

[Mikovitz, Colleen (LARC-E302)[Science Systems & Applications, Inc.]]

Dear Muhammad,

You can use the draw string command in your script file, something like:

'draw string 9 8 Temporal Corr = 'tcorr

Dear Gradsusr,
I have calculated NINO3.4 and NAO indices over a time period (1940-2010) and have plotted them as a linear plot over the desired time period. After plotting these NINO3.4 and NOA variables, I have computed their correlation which will be a number like "0.8" etc which I would like to display/write on the above GrADS shown plot. I used the GrADS function "tcorr" as follows
'open file.ctl'  **file that contains 1-d NINO34 and NAO variables for the period 1940-2010
'set t 1 last'  ****time from jan1940 till jan2010
'd nino34'
'd nao'
'set t 1'
'define tcorr=tcorr(NINO34,NAO,time=jan1941,time=jan2010)'
*As NINO34 and NAO are one dimensional and the correlation between them is a numerical number. I want to display this numerical value "tcorr" on the above-displayed plot (somewhere on the top right side, etc). How can I do that? Please advise.
