These locations can be changed by ## calling @code{thetaticks} with a vector of tick values. Note: ascending ## order is not required. ## ## If the first argument @var{hax} is an axes handle, then operate on ## this axis rather than the current axes returned by @code{gca}. ## ## Requesting a return value when calling @code{thetaticks} to set a property ## value will result in an error. ## ## NOTE: Octave does not currently implement polaraxes objects. It is ## therefore not possible to query or set a @qcode{"mode"} for the ## @qcode{"thetatick"} property as can be done with the equivalent functions ## for @var{x}, @var{y}, and @var{z} axes. ## ## @seealso{rticks, xticks, yticks, zticks, polar, get, set} ## @end deftypefn ## Author: Nicholas Jankowski <jankowskin@asme.org> ## Created: 2017-08-24 function retval = thetaticks (varargin) ## FIXME: Update function to work with polaraxes objects once that function ## is implemented in Octave.
