Dear Mary,

Thanks for your mail. I have added the codes as in your last mail in

my script. On executing the script, I got extra information as

follows,

(0) Working on time: 2013-02-15_18:00:00

(0) ymin_ter / ymax_ter = 800/6000

(0) ymin_tc / ymax_tc = 0/29

(0) ymin_rh / ymax_rh = 0/29

(0) ymin_tc2 / ymax_tc2 = 0/29

(0) ymin_rh2 / ymax_rh2 = 0/29

(0) ymin_vct / ymax_vct = 0/29

(0) Working on time: 2013-02-15_19:00:00

(0) ymin_ter / ymax_ter = 800/6000

(0) ymin_tc / ymax_tc = 0/29

(0) ymin_rh / ymax_rh = 0/29

(0) ymin_tc2 / ymax_tc2 = 0/29

(0) ymin_ to rh2 / ymax_rh2 = 0/29

(0) ymin_vct / ymax_vct = 0/29

(0) Working on time: 2013-02-15_20:00:00

(0) ymin_ter / ymax_ter = 800/6000

(0) ymin_tc / ymax_tc = 0/29

(0) ymin_rh / ymax_rh = 0/29

(0) ymin_tc2 / ymax_tc2 = 0/29

(0) ymin_rh2 / ymax_rh2 = 0/29

(0) ymin_vct / ymax_vct = 0/29

The plot generated by the script has clearly mentioned that the

Potential Temperature contours : 298 to 317 by 1 but ymin_tc /

ymax_tc = 0/29.

Can you help to manage my codes ?
