Bill, The axis arguments are, from what I understand, built somewhat as they go. The first digit generally groups the options in to broad categories, with the second specifying more detail. If you want detailed control over the axis options you can use the -2 option for the axis (or specify the plot window manually using plwind - see PLplot example 1 and several others). You can then use plbox to draw the bounds and tick marks for the plot window, potentially applying different options to each axis. In addition to a fairly raw binding of the plbox function, the OCaml bindings have an interface to specify a list of custom axis options (Major_grid, Minor_grid, Major_ticks, Minor_ticks, ...) which map to the characters which make up an underlying plbox option string. Something similar may work for Smalltalk as well.
