title: FusionCharts XT - Show value only when Mouse Over (MSLine2D Graph)
body: <p>I am trying to show values only when mouse over that point in the graph.
  Is that possible?
  Because I couldn't find any solution in the fusion charts Documentation..
  This is my code:</p>
  
  <pre><code>public function Generate_MSChart($category, $data, $chart, $width, $height, $str_params=false) 
  { 
      $FC =  FusionCharts($chart, $width, $height);  
      $FC-&gt;enablePrintManager();
      $FC-&gt;setRenderer('javascript');
  
      // Default str params
      if ($str_params === false) {
          $strParam="bgColor=F4F4F6,F4F4F6;showValues=0;showBorder=0;palette=2;numvdivlines=10;drawanchors=0;divlinealpha=30;alternatehgridalpha=20;setadaptiveymin=1;";
      }
  
      // Set chart attributes 
      $FC-&gt;setChartParams($strParam);
  
      // Add category names
      foreach ($category as $ct) {
          $FC-&gt;addCategory($ct);
      }
  
      // Add data
      foreach ($data as $dtk =&gt; $dte) {
          $FC-&gt;addDataset($dtk, "");
  
          foreach ($dte as $elm) {
              $FC-&gt;addChartData($elm);
          }
      }
  
      return $FC;
  }
  </code></pre>
  
  <p>As you can see I am using the ShowValues=0 Because my graph has alot of data in it.
  and if im showing the values it won't be readable!</p>
  
  <p>So what can I do to see the currect graph point value when mouseover? </p>
