title: How to add extra columns in multi-series Column Chart in FusionCharts
body: <p>I want to show few Bars in the Begining of the graph Which should be excluded in multi-series Column Chart,</p>
  
  <p>Like (A1,A2,A3,A4), Q1(CurrentYear, PreviousYear), Q2(CurrentYear, PreviousYear), Q3(CurrentYear, PreviousYear), Q4(CurrentYear, PreviousYear)</p>
  
  <p>Assuming A1,A2,A3,A4 are Bars to be shown first, Then Q1,Q2,Q3,Q4 are the categories as usual for the multi-Series Column Chart.</p>
  
  <p>I'm using the XML code right now as follows,</p>
  
  <pre><code> &lt;chart caption="Sales in Last Two Years" subcaption="Quarter-wise comparison" xaxisname="Quarter" yaxisname="Sales (In USD)" numberprefix="$" theme="fint"&gt;
  &lt;categories&gt;
  &lt;category label="Q1" /&gt;
  &lt;category label="Q2" /&gt;
  &lt;category label="Q3" /&gt;
  &lt;category label="Q4" /&gt;
  &lt;/categories&gt;
  &lt;dataset seriesname="Previous Year"&gt;
  &lt;set value="10000" /&gt;
  &lt;set value="11500" /&gt;
  &lt;set value="12500" /&gt;
  &lt;set value="15000" /&gt;
  &lt;/dataset&gt;
  &lt;dataset seriesname="Current Year"&gt;
  &lt;set value="25400" /&gt;
  &lt;set value="29800" /&gt;
  &lt;set value="21800" /&gt;
  &lt;set value="26800" /&gt;
  &lt;/dataset&gt;
  &lt;/chart&gt;
  </code></pre>
  
  <p>I want to display Four columns as first four column , which should not be the part of multi-series Column Chart.</p>
  
  <p>How can it be done?</p>
  
  <p>Thanks.!</p>
