<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, e.g., 10, and it picks axis
limits and ticks that are multiples of your base.</p>

<p>Dynamically find minor tick positions based on the positions of
major ticks. Assumes the scale is linear and major ticks are
evenly spaced.</p>
<p><em>n</em> is the number of subdivisions of the interval between
major ticks; e.g., n=2 will place a single minor tick midway
between major ticks.</p>
<p>If <em>n</em> is omitted or None, it will be set to 5 or 4.</p>
