considering shuffle: function as an element in the array (fixed)

[crollioac]

for(var val in legendArr){

        if(val != "shuffle"){
            legend += "<div id='legend"+legendArr[val][3]+"' style='overflow: hidden; zoom: 1;'>";
            legend += "<div class='legendBar"+legendArr[val][2]+"' id='legendColor"+legendArr[val][3]+"' style='background-color:"+legendArr[val][0]+"'></div>";
            legend += "<div class='legendLabel"+legendArr[val][2]+"' id='graphLabel"+unique+"'>"+legendArr[val][1]+"</div>";
            legend += "</div>";         
    }
}

add an if statement which checks for the [shuffle: function] in an array.

and also in loop
