Usage</h1>
<p>To add a <a class="el" href="classQCPBars.html" title="A plottable representing a bar chart in a plot. ">QCPBars</a> plottable to the group, create a new group and then add the respective bars intances: </p>
<div class="fragment"><div class="line"> <a class="code" href="classQCPBarsGroup.html">QCPBarsGroup</a> *group = <span class="keyword">new</span> <a class="code" href="classQCPBarsGroup.html#aa4e043b9a22c6c5ea0f93740aca063e1">QCPBarsGroup</a>(customPlot);</div>
<div class="line"> group-><a class="code" href="classQCPBarsGroup.html#a809ed63cc4ff7cd5b0b8c96b470163d3">append</a>(bars1);</div>
<div class="line"> group-><a class="code" href="classQCPBarsGroup.html#a809ed63cc4ff7cd5b0b8c96b470163d3">append</a>(bars2);</div>
</div><!-- fragment --><p>Alternatively to appending to the group like shown above, you can also set the group on the <a class="el" href="classQCPBars.html" title="A plottable representing a bar chart in a plot. ">QCPBars</a> plottable via <a class="el" href="classQCPBars.html#aedd1709061f0b307c47ddb45e172ef9a">QCPBars::setBarsGroup</a>.</p>
<p>The spacing between the bars can be configured via <a class="el" href="classQCPBarsGroup.html#a2c7e2d61b10594a4555b615e1fcaf49e">setSpacingType</a> and <a class="el" href="classQCPBarsGroup.html#aa553d327479d72a0c3dafcc724a190e2">setSpacing</a>. The bars in this group appear in the plot in the order they were appended. To insert a bars plottable at a certain index position, or to reposition a bars plottable which is already in the group, use <a class="el" href="classQCPBarsGroup.html#a309a5f7233db189f3ea9c2d04ece6c13">insert</a>.</p>
<p>To remove specific bars from the group, use either <a class="el" href="classQCPBarsGroup.html#a215e28a5944f1159013a0e19169220e7">remove</a> or call <a class="el" href="classQCPBars.html#aedd1709061f0b307c47ddb45e172ef9a">QCPBars::setBarsGroup(0)</a> on the respective bars plottable.</p>
<p>To clear the entire group, call <a class="el" href="classQCPBarsGroup.html#a3ddf23928c6cd89530bd34ab7ba7b177">clear</a>, or simply delete the group.</p>
