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

Dear NCL users,

I created a contour plot by gsn_csm_contour_map, where the labels in the color bar are hard to see because I used  res at lbLabelFontHeightF  = 0.005. The figure is attached. If I change the value of lbLabelFontHeightF to 0.007 only the every second label are noted. I also created a panel plot with the same script and used:

resP at gsnPanelLabelBar    = True                ; add common color bar
resP at lbLabelFontHeightF  = 0.007               ; make labels smaller

I got nice colorbar labels. The figure is attached. Could someone suggest me a solution to fix the color bar size in the case of gsn_csm_contour_map? The script is attached, as well.

Thank you for your help in advance!

Kind regards,
Beata
