Although the locators know nothing about major or minor ticks, they are used by the Axis class to support major and minor tick locating and formatting. Generic tick locators and formatters are provided, as well as domain specific custom ones.. Tick locating ------------- The Locator class is the base class for all tick locators. The locators handle autoscaling of the view limits based on the data limits, and the choosing of tick locations. A useful semi-automatic tick locator is MultipleLocator. You initialize this with a base, eg 10, and it picks axis limits and ticks that are multiples of your base. The Locator subclasses defined here are :class:`NullLocator` No ticks :class:`FixedLocator` Tick locations are fixed :class:`IndexLocator` locator for index plots (eg. where x = range(len(y))) :class:`LinearLocator` evenly spaced ticks from min to max :class:`LogLocator` logarithmically ticks from min to max :class:`MultipleLocator` ticks and range are a multiple of base; either integer or float :class:`OldAutoLocator` choose a MultipleLocator and dyamically reassign it for intelligent ticking during navigation :class:`MaxNLocator` finds up to a max number of ticks at nice locations :class:`AutoLocator` :class:`MaxNLocator` with simple defaults. This is the default tick locator for most plotting. There are a number of locators specialized for date locations - see the dates module You can define your own locator by deriving from Locator. You must override the __call__ method, which returns a sequence of locations, and you will probably want to override the autoscale method to set the view limits from the data limits. If you want to override the default locator, use one of the above or a custom locator and pass it to the x or y axis instance. The relevant methods are:: ax.xaxis.set_major_locator( xmajorLocator ) ax.xaxis.set_minor_locator( xminorLocator ) ax.yaxis.set_major_locator( ymajorLocator ) ax.yaxis.set_minor_locator( yminorLocator ) The default minor locator is the NullLocator, eg no minor ticks on by default. Tick formatting --------------- Tick formatting is controlled by classes derived from Formatter. The formatter operates on a single tick value and returns a string to the axis. :class:`NullFormatter` no labels on the ticks :class:`IndexFormatter` set the strings from a list of labels :class:`FixedFormatter` set the strings manually for the labels :class:`FuncFormatter` user defined function sets the labels :class:`FormatStrFormatter` use a sprintf format string :class:`ScalarFormatter` default formatter for scalars; autopick the fmt string :class:`LogFormatter` formatter for log axes You can derive your own formatter from the Formatter base class by simply overriding the ``__call__`` method. The formatter class has access to the axis view and data limits. To control the major and minor tick label formats, use one of the following methods:: ax.xaxis.set_major_formatter( xmajorFormatter ) ax.xaxis.set_minor_formatter( xminorFormatter ) ax.yaxis.set_major_formatter( ymajorFormatter ) ax.yaxis.set_minor_formatter( yminorFormatter ) See :ref:`pylab_examples-major_minor_demo1` for an example of setting major an minor ticks. See the :mod:`matplotlib.dates` module for more information and examples of using date locators and formatters. i(tdivisionN(trcParams(tcbook(t transformst TickHelpercB sNeZdZdddYZdZdZdZdZdZ RS( t DummyAxiscB s5eZdZdZdZdZdZRS(cC s(tii|_tii|_dS(N(t mtransformstBboxtunittdataLimtviewLim(tself((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyt__init__scC s |iiS(N(R t intervalx(R ((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytget_view_intervalscC s||f|i_dS(N(R R (R tvmintvmax((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytset_view_intervalscC s |iiS(N(R R (R ((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytget_data_intervalscC s||f|i_dS(N(R R (R RR((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytset_data_intervals(t__name__t __module__R RRRR(((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyRs     cC s ||_dS(N(taxis(R R((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytset_axisscC s'|idjo|i|_ndS(N(RtNoneR(R ((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytcreate_dummy_axisscC s|ii||dS(N(RR(R RR((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyRscC s|ii||dS(N(RR(R RR((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyRscC s$|i|||i||dS(N(RR(R RR((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyt set_boundssN(( RRRRRRRRRR(((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyRs    t FormattercB sMeZdZgZddZdZdZdZdZ dZ RS(s/ Convert the tick location to a string cC stddS(sPReturn the format for tick val x at position pos; pos=None indicated unspecifiedsDerived must overideN(tNotImplementedError(R txtpos((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyt__call__scC s |i|S(N(R(R tvalue((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyt format_datascC s |i|S(sreturn a short string version(R!(R R ((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytformat_data_shortscC sdS(Nt((R ((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pyt get_offsetscC s ||_dS(N(tlocs(R R%((sD/opt/alt/python27/lib64/python2.7/site-packages/matplotlib/ticker.pytset_locsscC s|S(s some classes may want to replace a hyphen for minus with the proper unicode symbol as described `here `_.
