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
<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.ncl.ucar.edu_Applications_contourLab.shtml-23ex8&d=BQMFaQ&c=qHNyRuJKHYeI-vwTnTfWXq4fkZpyjWUA1LcPL7eQSSQ&r=6RmpIe4P-G8omsHqYS85uBS-3JaNVk3lvOG-hmdOrr8&m=t3odcgioPsQgU6JRWvsdVwd0gwOEVV5hMSrdBndd3Mo&s=ZNuQ_nbWpHAZoQA2TihMpeuz17r-dKyP9ToS_3sKHC4&e=>

This example uses:


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

Hi, there,

I am doing contour lines, and want to label those lines properly.
I need the line label's to have one decimal, so I set.
res at cnLineLabelFormat      = "%6.1f"
But it seems it did not work well, but only have the integers.

Here is the part of the resource:

   res at cnMinLevelValF            = 1010.0
  res at cnMaxLevelValF            = 1020.0
  res at cnLineLabelInterval     = 1
  res at cnLevelSpacingF           = 0.5
  res at cnLineLabelFormat      = "%6.1f"

What I hope to get the line labels to have:
1015.0, 1015.5, 1016.0
Not (as it happens now):
1015 1015 1016.

Thanks,

Wei Huang
