<div class="textblock"><p>A margin group allows synchronization of margin sides if working with multiple layout elements. </p>
<p><a class="el" href="class_q_c_p_margin_group.html" title="A margin group allows synchronization of margin sides if working with multiple layout elements...">QCPMarginGroup</a> allows you to tie a margin side of two or more layout elements together, such that they will all have the same size, based on the largest required margin in the group.</p>
<p><br />
</p><div class="image">
<img src="QCPMarginGroup.png" alt="QCPMarginGroup.png"/>
<div class="caption">
Demonstration of QCPMarginGroup</div></div>
<p><br />
 In certain situations it is desirable that margins at specific sides are synchronized across layout elements. For example, if one <a class="el" href="class_q_c_p_axis_rect.html" title="Holds multiple axes and arranges them in a rectangular shape. ">QCPAxisRect</a> is below another one in a grid layout, it will provide a cleaner look to the user if the left and right margins of the two axis rects are of the same size. The left axis of the top axis rect will then be at the same horizontal position as the left axis of the lower axis rect, making them appear aligned. The same applies for the right axes. This is what <a class="el" href="class_q_c_p_margin_group.html" title="A margin group allows synchronization of margin sides if working with multiple layout elements...">QCPMarginGroup</a> makes possible.</p>
<p>To add/remove a specific side of a layout element to/from a margin group, use the <a class="el" href="class_q_c_p_layout_element.html#a516e56f76b6bc100e8e71d329866847d">QCPLayoutElement::setMarginGroup</a> method. To completely break apart the margin group, either call <a class="el" href="class_q_c_p_margin_group.html#a144b67f216e4e86c3a3a309e850285fe">clear</a>, or just delete the margin group.</p>
<h1><a class="anchor" id="QCPMarginGroup-example"></a>

<p>First create a margin group: </p><div class="fragment"><div class="line"><a class="code" href="class_q_c_p_margin_group.html">QCPMarginGroup</a> *group = <span class="keyword">new</span> <a class="code" href="class_q_c_p_margin_group.html#ac481c20678ec5b305d6df330715f4b7b">QCPMarginGroup</a>(customPlot);</div>
</div><!-- fragment --><p> Then set this group on the layout element sides: </p><div class="fragment"><div class="line">customPlot-&gt;axisRect(0)-&gt;setMarginGroup(<a class="code" href="namespace_q_c_p.html#a7e487e3e2ccb62ab7771065bab7cae54a9500c8bfcc9e80b9dff0a8e00e867f07">QCP::msLeft</a>|<a class="code" href="namespace_q_c_p.html#a7e487e3e2ccb62ab7771065bab7cae54a93c719593bb2b94ed244d52c86d83b65">QCP::msRight</a>, group);</div>
<div class="line">customPlot-&gt;axisRect(1)-&gt;setMarginGroup(<a class="code" href="namespace_q_c_p.html#a7e487e3e2ccb62ab7771065bab7cae54a9500c8bfcc9e80b9dff0a8e00e867f07">QCP::msLeft</a>|<a class="code" href="namespace_q_c_p.html#a7e487e3e2ccb62ab7771065bab7cae54a93c719593bb2b94ed244d52c86d83b65">QCP::msRight</a>, group);</div>
