Re: plot circle in contour map

Hi Dennis; Thanks for your reply. If I can do as the following example is also ok. http://www.ncl.ucar.edu/Applications/Scripts/polyg_8.ncl  Location of the circle/point as I said before and then classify the color into 3 color only based on the size in the third column. Again, thank you.

You must repeat the last point to complete the circle.   lat = (/7.4, 5.7, ... , 6.5, 7.4/)   lon = (/126.5, 156.6, ..., 81.7, 126.5/) On 5/24/12 12:02 PM, juki juki wrote: > Dear all, > > I want plot circles in a contourmap in 70-160E and 10S-10N.
