As my earlier post had no heading, I am reposting the same in the hope that<br>
it may be seen and I can get help.<br>
I hope someone can find time to explain to me a few things on panel plots.<br>
In the <a href="http://panles_demo.gs/" target="_blank">panles_demo.gs</a> (snippet below),I do not understand the following:<br>
<br>
1. for four plots on a page I loop through p=1 to p=4, why do we display t<br>
(I want to display what I have in my file;<br>
2. what is the global variable defined by _vpg.p in this script?<br>
3. How do I put a title corresponding to the graphic validity time, on each<br>
plot?<br>
Help will be appreciated.<br>

Good Morning:<br>
<br>
This is Uzair Mannan from Pakistan.. I was<br>
searching on how to extract temperature and precipitation variable data<br>
from GrADS.<br>
<br>
The problem is when I copy and save the fprintf script to <a href="http://fprintf.gs/" target="_blank">fprintf.gs</a> and ran GrADS in order to run the file test_001_SRF.1990010100.nc.ctl it says:-<br>
<br>
ga-> fprintf ts ts.txt<br>
Unknown command: fprintf<br>
<br>
<br>
<br>
I'm using Linux Ubuntu 12.04 LTS and GrADS 2.0.a9 and have downloaded the coding of fprintf script from<br>
<br>
<a href="http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file" target="_blank">http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file</a><br>
<br>
What is the issue?? Where to save the <a href="http://fprintf.gs/" target="_blank">fprintf.gs</a> file in order to get the script workable ???<br>
<br>

Hi Uzair,<br>
<br>
Try revising this 2 points:<br>
<br>
1) Have you placed fprintf between ' '. I mean in this way: 'fprintf ts<br>
ts.txt' in your script<br>
<br>
2) Are you sure you have saved fprintf in the proper directory ?<br>
<br>
I hope this could help.<br>
Cheers,<br>
<br>
Hern?n<br>

Install open grads instead of grads2.9b. Then it will work.<br>

Ver. 2.9b? I guess this version is not yet released. <a href="http://fprintf.gs/" target="_blank">fprintf.gs</a> will work for ver-1.9 also. It needs 'gxout print' option which is available since ver. 1.9.<br>

The display of variable 't' in the panels_demo script is only for demonstration purposes. Of course, you can plot any variable or expression you want to.<br>

That is a script variable that contains the 'set vpage' command for panel number p.<br>
<br>

One way to do this is to invoke 'q time' and parse the output to get a string that specifies the time that corresponds to your plot and then use 'set string' and 'draw string' to draw it above your plot. Below is a code snippet that I use for this purpose:<br>
<br>
function mydate<br>
'query time'<br>
sres = subwrd(result,3)<br>
wday = subwrd(result,6)<br>
i = 1<br>
while (substr(sres,i,1)!='Z')<br>
i = i + 1<br>
endwhile<br>
hour = substr(sres,1,i)<br>
isav = i<br>
i = i + 1<br>
while (substr(sres,i,1)>='0' & substr(sres,i,1)<='9')<br>
i = i + 1<br>
endwhile<br>
day = substr(sres,isav+1,i-isav-1)<br>
month = substr(sres,i,3)<br>
year = substr(sres,i+3,4)<br>
return (hour' 'wday' 'day' 'month' 'year)<br>
<br>
