Re: [ferret_users] problem with longitude lines drawing

[Russ Fiedler <russell.fiedler@xxxxxxxx>]

Hi,

Your array isn't symmetric. The North pole is at i=29,j=33

Try

con/i=1:57/j=1:65 tlong
con/i=1:57/j=1:65/ov tlat


That chops off the extra points in both directions.

Alternatively to just centre the plot

con/hlimits=`700+700-780+2*29`:780/vlimits=`380+380-460+2*33`:460 tlong
con/hlimits=`700+700-780+2*29`:780/vlimits=`380+380-460+2*33`:460/ov tlat

Dear Ferreters,

I'm trying to draw longitude/latitude from data set (tlat, tlong):

set data File1.nc

contour tlat

contour/ov tlong

The problem is that longitude lines don't finish in the middle - on the pole - but they are multiplicated in one direction - as in attached picture. How can I fix it?

I'm absolutely new to Ferret (I'm usingv6.93) Thanks in advance for your tips!
