[ncl-talk] plotting in Cygwin

[yuuum]

Hi NCL,

I'm plotting figures in Cygwin. 
$ uname -a
CYGWIN_NT-6.1 Miao-PC 1.7.32(0.274/5/3) 2014-08-13 23:03 i686 Cygwin

The figure I got is like that shown in the attached file of CygwinFig.jpg. I also produced this figure using Linux before. It's shown in LinuxFig.jpg.

My problem is the figure produced in Cygwin looks a little weird compared to that produced in Linux. There seems to have black or gray lines at the boundary of color filled grids.  The figure produced in Linux is a little blurry but should be right. Is there any problem with my computer setting? What may cause this problem and how can I fix it?

Thanks and best regards!
Miao
