<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qabstractbarseries.html">QAbstractBarSeries</a> class is an abstract parent class for all bar series classes.</p>
<p>In bar charts, bars are defined as bar sets that contain one data value for each category. The position of a bar is specified by the category and its height by the data value. Bar series that contain multiple bar sets group together bars that belong to the same category. The way the bars are displayed is determined by the subclass of this class chosen to create the bar chart.</p>
<p>If a <a href="qvalueaxis.html">QValueAxis</a> is used instead of <a href="qbarcategoryaxis.html">QBarCategoryAxis</a> for the main bar axis, the bars are grouped around the index value of the category.</p>
<p>See the <a href="qtcharts-barchart-example.html">bar chart example</a> to learn how to use the <a href="qbarseries.html">QBarSeries</a> class to create a simple bar chart.</p>

<p>The unit of width is the unit of the x-axis. The minimum width for bars is zero, and negative values are treated as zero. Setting the width to zero means that the width of the bar on the screen is one pixel regardless of the scale of the x-axis. Bars wider than zero are scaled using the x-axis scale.</p>

<p>This property holds the format used for showing labels in a bar series.</p>

<p>For example, the following usage of the format tags would produce labels that show the value followed by the unit (u):</p>
<pre class="cpp">

  series<span class="operator">-</span><span class="operator">&gt;</span>setLabelsFormat(<span class="string">&quot;@value u&quot;</span>);

</pre>
<p>By default, the labels show the value of the bar. For the percent bar series, <i>%</i> is added after the value. The labels are shown on the plot area, whereas labels on the edge of the plot area are cut. If the bars are close to each other, the labels may overlap.</p>
