[ncl-talk] improve the color bar labels

[Mary Haley]

Dear Beata,

This is one of those cases where you have to set two resources.

First, the "lbLabelAutoStride" resource is set to True by default, which
means NCL tries to determine a "nice" stride for your labelbar labels,
depending on many factors.  This is the thing that is causing your label
stride to change when you increase your font size, because it probably
thinks the labels are too close together. This resource overrides any
setting for lbLabelStride.

So, you need to set both:

res at lbLabelAutoStride = False
res at lbLabelStride = 1
