hi,

I have an unusuall question...

I have a file of x and y coordinates of a contour (on irregular grid).

I managed to fill the contour with "gsn_add_polygon"

.

.

.

xy = gsn_xy(wks,x,y,res)

.

.

.

dum = gsn_add_polygon(wks, xy, x, y, gsres)

.

.

.

draw(xy)

My question is, what is exactly xy after I call gsn_add_contour ? Is it

an array of x and y coordinates of all the points inside the contour?

If it is, I assume that the contour is somehow interpolated on a

regular grid and then there is an algorithm to fill the points inside

the contour. If so, what is the resolution of the grid? Can I controll

it?

If I'm completely wrong, is there a way in NCL to get such an array

(array of x and y coordinates of all the points inside the contour)?

Thanks,

Roni
