Hi Sergei:

We try to exercise most of our API in our standard examples.  So look
in

examples/<language>/x*

for good example code in the language of your choice.

And to answer your specific question, I am not that familiar with use
of custom axes, but

examples/c/x19c.c

does have a comment:

// A custom axis labeling function for longitudes and latitudes.

so you might want to look at standard example 19 in the language of
your choice to start.

Thanks for your interest in PLplot, and good luck with using it further.

Alan
