<p class="MsoNormal">I have to admit that this one stumped me. It is much easier to do this using the gsn_csm_contour_map function in NCL, because that function is reconstructing the labelbar from scratch, and it explicitly allows you to change this resource.<o:p></o:p></p>

<p class="MsoNormal">PyNGL, on the other hand, is using the default labelbar that's provided when you create a contour plot, and apparently this default doesn't like you trying to change the label strings.<o:p></o:p></p>
