title: How to show tooltip/value over bar chart?
body: <p>I am using <em>iReport 4.7 Community Edition</em> for making reports. And I'm using <em>Chrome</em> browser for viewing it in HTML format.</p>
  
  <p>I put 3D bar chart in summary band and want to show value on its tip (i.e. on top). So I go by below way:</p>
  
  <p>1) check on <code>show Labels</code> &amp;  <code>show Legends</code> in 3D Bar Chart Properties.</p>
  
  <p>2) Right click on Chart > Chart Details > Details > Category Details > by selecting category,Modify > Item Hyper link > Tool tip > Tool tip Expression > <code>$F{dayname(ServiceDate)}.toString()</code> , where <code>$F{dayname(ServiceDate)}</code> is field name</p>
  
  <p>even though, its not showing anything.</p>
  
  <p>Is this facility not present in community edition? Should I embed any other <em>.jar</em> file for that?</p>
