<h2>Tick locating and formatting<a class="headerlink" href="#tick-locating-and-formatting" title="Permalink to this headline">¶</a></h2>
<p>This module contains classes for configuring tick locating and formatting.
Generic tick locators and formatters are provided, as well as domain specific
custom ones.</p>
<p>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.</p>

<h3>Tick locating<a class="headerlink" href="#tick-locating" title="Permalink to this headline">¶</a></h3>
<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
<a class="reference internal" href="#matplotlib.ticker.MultipleLocator" title="matplotlib.ticker.MultipleLocator"><code class="xref py py-obj docutils literal notranslate"><span class="pre">MultipleLocator</span></code></a>. It is initialized with a base, e.g., 10, and it picks
axis limits and ticks that are multiples of that base.</p>
<p>The Locator subclasses defined here are</p>

<p>There are a number of locators specialized for date locations - see
the <a class="reference internal" href="dates_api.html#module-matplotlib.dates" title="matplotlib.dates"><code class="xref py py-mod docutils literal notranslate"><span class="pre">dates</span></code></a> module.</p>
<p>You can define your own locator by deriving from Locator. You must
override the <code class="docutils literal notranslate"><span class="pre">__call__</span></code> 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>

<p>You can derive your own formatter from the Formatter base class by
simply overriding the <code class="docutils literal notranslate"><span class="pre">__call__</span></code> method. The formatter class has
access to the axis view and data limits.</p>

<p><strong>Offset notation and scientific notation</strong></p>
<p>Offset notation and scientific notation look quite similar at first sight.
Both split some information from the formatted tick values and display it
at the end of the axis.</p>
<ul class="simple">
<li>The scientific notation splits up the order of magnitude, i.e. a
multiplicative scaling factor, e.g. <code class="docutils literal notranslate"><span class="pre">1e6</span></code>.</li>
<li>The offset notation separates an additive constant, e.g. <code class="docutils literal notranslate"><span class="pre">+1e6</span></code>. The
offset notation label is always prefixed with a <code class="docutils literal notranslate"><span class="pre">+</span></code> or <code class="docutils literal notranslate"><span class="pre">-</span></code> sign
and is thus distinguishable from the order of magnitude label.</li>
</ul>
<p>The following plot with x limits <code class="docutils literal notranslate"><span class="pre">1_000_000</span></code> to <code class="docutils literal notranslate"><span class="pre">1_000_010</span></code> illustrates
the different formatting. Note the labels at the right edge of the x axis.</p>

<p>The <a class="reference internal" href="#matplotlib.ticker.LogFormatter.set_locs" title="matplotlib.ticker.LogFormatter.set_locs"><code class="xref py py-obj docutils literal notranslate"><span class="pre">set_locs</span></code></a> method must be called to enable the subsetting
logic controlled by the <code class="docutils literal notranslate"><span class="pre">minor_thresholds</span></code> parameter.</p>
<p>In some cases such as the colorbar, there is no distinction between
major and minor ticks; the tick locations might be set manually,
or by a locator that puts ticks at integer powers of base and
at intermediate locations. For this situation, disable the
minor_thresholds logic by using <code class="docutils literal notranslate"><span class="pre">minor_thresholds=(np.inf,</span> <span class="pre">np.inf)</span></code>,
so that all ticks will be labeled.</p>
<p>To disable labeling of minor ticks when 'labelOnlyBase' is False,
use <code class="docutils literal notranslate"><span class="pre">minor_thresholds=(0,</span> <span class="pre">0)</span></code>. This is the default for the
"classic" style.</p>
<p class="rubric">Examples</p>
<p>To label a subset of minor ticks when the view limits span up
to 2 decades, and all of the ticks when zoomed in to 0.5 decades
or less, use <code class="docutils literal notranslate"><span class="pre">minor_thresholds=(2,</span> <span class="pre">0.5)</span></code>.</p>
<p>To label all minor ticks when the view limits span up to 1.5
decades, use <code class="docutils literal notranslate"><span class="pre">minor_thresholds=(1.5,</span> <span class="pre">1.5)</span></code>.</p>
