Re: time_lon plot problem.

Hi Kyle,

The cd_string.ncl not being included in V6.1.0-beta is my fault. I fixed this so it will be available for all binaries in 6.1.0.

Meanwhile I've attached it here.

In your next script, you create a brand new resource and give that to the procedure. If you plotted gsn_csm_contour with 'resPlot', you would get the axis right, but without the additional resources you set in 'res'.

While some older versions of code still include tTick, it is no longer included in releases of NCL, thus leading to your problem.
