<h3>Tick locating and formatting<a class="headerlink" href="#tick-locating-and-formatting" title="Permalink to this headline">¶</a></h3>
<p>This module contains classes to support completely configurable tick locating
and formatting. 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..</p>
<div class="section" id="tick-locating">
<h4>Tick locating<a class="headerlink" href="#tick-locating" title="Permalink to this headline">¶</a></h4>
<p>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.</p>
<p>The Locator subclasses defined here are</p>

</dl>
<p>There are a number of locators specialized for date locations - see
the dates module</p>
<p>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.</p>
<p>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:</p>
