回答1:

You do this by attaching a handler to the legendItemClick event and just returning false. This will prevent the default action which is to toggle the pie sector.

point: {
    events: {
        legendItemClick: function () {
            return false; // <== returning false will cancel the default action
        }
    }
}

See this example http://jsfiddle.net/mfras3r/3vVGB/1/

pie: {
   showInLegend: true,
   allowPointSelect: false,
   point:{
       events : {
        legendItemClick: function(e){
            e.preventDefault();
        }
       }
   }
 }
