High Low value text display

Hi,

Could anyone help me to know how to print the integer part of High Label in contour drawing ?

I attached my drawing in this e-mail, as you see the text value like 8.7, I want to make this to 9.
( For example 2.3 -> 2, 3.5 -> 4 etc. )

Also in this drawing, zero line is a bit thicker than other lines. How to make all lines are same style in wrf_contour function ? ( I also want to use same line style for negative values. )

Thanks in advance.

Best regards,

John Hyun
