title: Remove grid and border from p:chart barchart
body: <p>I am trying to remove the grid and border in my barchart of primefaces.
  Please think about the new charts of primefaces. I googled a lot and only have found solutions for the old tags of primefaces but there are new ones. </p>
  
  <pre><code>&lt;p:chart type="bar" model="#{reportServerController.horizontalBarModelG}" styleClass="chartSize" &gt;
              &lt;p:ajax event="itemSelect" listener="#{auftragBean.itemSelectGutachten}" update="dataTableG" /&gt;
          &lt;/p:chart&gt;
  </code></pre>
  
  <p>So is there a possibility to remove the border and grid from the chart?</p>
