You've chosen a rather tricky example to work from, using logarithmic  
scales and using few features of the most basic axes commands. Ticks  
are controlled by Dx, Dy, dx, dy and the axes crossing point. If Dx is  
omitted, it defaults to 1. If dx is omitted, it defaults to Dx*xunit.  
Ticks on x axis are placed dx apart, starting at the axes crossing  
point. A label is placed at each, with value Ox (default 0) and  
incrementing by Dx. If 'texdoc pstricks' doesn't work for you, try  
some of the examples from
