[ncl-talk] contour line label format

[Mary Haley]

Hi Wei,

The xxYYYYFormat resources don't work like the formatting in sprintf or
sprinti.

Please see this tickmark formatting example image, which shows what the
different strings are you can use:

You can also read this description:

I created a new example, since we didn't have any that use this resource:

http://www.ncl.ucar.edu/Applications/contourLab.shtml#ex8

This example uses:

  res at cnLineLabelFormat    = "0@;*.3f"                      ; Only one
value after decimal point
