Hello

The getLegendSize function return the size of the data series name, wich is not useful for the pie chart legend.
How can I obtain the size of pie chart legend?

best regards

Hello

I work around in this way:

Code:
      $legParms = array("Style"=>LEGEND_ROUND,"Mode"=>LEGEND_VERTICAL);
      $maxLabelWidth = 0;      // search legend width
      foreach($dt->getValues("Labels") as $v) {
         $dt->setSerieDescription($legend,$v);
         $Size = $graph->getLegendSize($legParms);
         $maxLabelWidth = max($maxLabelWidth,$Size["Width"]);
      }      
      $dt->setSerieDescription($legend,$legend);      // Restore original legend

$legend is a variable wich contains the data name

this fragment is part of my pChart "wrapper"

best regards
