<div class="textblock"><p>Specialized axis ticker with a fixed tick step. </p>
<div class="image">
<img src="axisticker-fixed.png" alt="axisticker-fixed.png"/>
</div>
<p>This <a class="el" href="classQCPAxisTicker.html" title="The base class tick generator used by QCPAxis to create tick positions and tick labels. ">QCPAxisTicker</a> subclass generates ticks with a fixed tick step set with <a class="el" href="classQCPAxisTickerFixed.html#a4bc83d85a4f81d4abdd3fa5042d7b833">setTickStep</a>. It is also possible to allow integer multiples and integer powers of the specified tick step with <a class="el" href="classQCPAxisTickerFixed.html#acbc7c9bcd80b3dc3edee5f0519d301f6">setScaleStrategy</a>.</p>
<p>A typical application of this ticker is to make an axis only display integers, by setting the tick step of the ticker to 1.0 and the scale strategy to <a class="el" href="classQCPAxisTickerFixed.html#a15b3d38b935d404b1311eb85cfb6a439a22f651785f6412645837421896561104">ssMultiples</a>.</p>
<p>Another case is when a certain number has a special meaning and axis ticks should only appear at multiples of that value. In this case you might also want to consider <a class="el" href="classQCPAxisTickerPi.html">QCPAxisTickerPi</a> because despite the name it is not limited to only pi symbols/values.</p>
