<DIV>Hi!</DIV>
<DIV></DIV>
<DIV>Is there any utility in GRADS to plot values only between two contour levels?</DIV>
<DIV></DIV>
<DIV>For example, I want to display ozone data over Indian region between the contour levels</DIV>
<DIV>180 - 200 DU? Is it possible to mask values above 200 and below 100?</DIV>
<DIV></DIV>
<DIV>Thanks in Advance.</DIV>
