Since that method takes a <code>QSharedPointer<QCPAxisTicker></code>, multiple axes can share the same ticker instance.</p>
<p>This base class generates normal tick coordinates and numeric labels for linear axes. It picks a reasonable tick step (the separation between ticks) which results in readable tick labels.

Creating own axis tickers</h1>
<p>Creating own axis tickers can be achieved very easily by sublassing <a class="el" href="classQCPAxisTicker.html" title="The base class tick generator used by QCPAxis to create tick positions and tick labels. ">QCPAxisTicker</a> and reimplementing some or all of the available virtual methods.</p>
<p>In the simplest case you might wish to just generate different tick steps than the other tickers, so you only reimplement the method <a class="el" href="classQCPAxisTicker.html#a910d69bcec2de37e92d8d4e1ecf201e2">getTickStep</a>. If you additionally want control over the string that will be shown as tick label, reimplement <a class="el" href="classQCPAxisTicker.html#a8201eb4aa8be192bf786b126eb5ee089">getTickLabel</a>.</p>
<p>If you wish to have complete control, you can generate the tick vectors and tick label vectors yourself by reimplementing <a class="el" href="classQCPAxisTicker.html#af4645a824c7bd2ca8fc7e86ebf9055bd">createTickVector</a> and <a class="el" href="classQCPAxisTicker.html#a804050e408f37a0b9770c6654ebe6aa7">createLabelVector</a>. The default implementations use the previously mentioned virtual methods <a class="el" href="classQCPAxisTicker.html#a910d69bcec2de37e92d8d4e1ecf201e2">getTickStep</a> and <a class="el" href="classQCPAxisTicker.html#a8201eb4aa8be192bf786b126eb5ee089">getTickLabel</a>, but your reimplementations don't necessarily need to do so. For example in the case of unequal tick steps, the method <a class="el" href="classQCPAxisTicker.html#a910d69bcec2de37e92d8d4e1ecf201e2">getTickStep</a> loses its usefulness and can be ignored.</p>
<p>The sub tick count between major ticks can be controlled with <a class="el" href="classQCPAxisTicker.html#a4ccc403ced7a1457ce6ba293509933c8">getSubTickCount</a>. Full sub tick placement control is obtained by reimplementing <a class="el" href="classQCPAxisTicker.html#a9a6435723fa0bd366d1ea4c2cff7c33f">createSubTickVector</a>.</p>
<p>See the documentation of all these virtual methods in <a class="el" href="classQCPAxisTicker.html" title="The base class tick generator used by QCPAxis to create tick positions and tick labels. ">QCPAxisTicker</a> for detailed information about the parameters and expected return values. </p>
