problem about label on potential temperature

Dear whom it may concern,

I want to give the value of potential temperature on my contour line
in my plot. Then, I tried to put these commands: lbLabelBarOn = True
or either cnConstFLabelOn = True , they did not work. Some of my plots
show off the label, but some did not though I used the same script.
Can you please give me any advices how to show off the label value in
all plots ?

Thank you so much in advance.

Best regards,
Manatchanok
