Mateus,

I checked the code for gsn_csm_xy, and apparently it is
explicitly turning off the Y axis string if the tickmarks
are explicitly labeled. I don't remember why this is
done, but I don't believe it's a bug. I will
document this.

To get a label, you can set:

    res_at_tiYAxisString = "...." ; or res_at_tiYAxisString =
y_at_long_name

Yes, it is possible. The key behind indicating which
tickmarks
you want labels on is to getting the tickmark values
(tmXBValues)
correct. If you are not seeing any labels, then
double-check
that you have the correct values for the axis you are
working
with. That is, make sure they are in the correct
range and have the correct units.
