Amchart 传奇正在循环播放

Question

我正在使用 Amcharts 显示图表图和带有图例的饼图，并从 json 文件中提取数据：

$(function() {

$.getJSON('http://107.170.203.64/jsonp.php?callback=?', function(data) { ... } ); });

这是我得到的 json 数据：

但是饼图的图例似乎在循环并显示两次标签：

// populate custom legend when chart renders
        chart.customLegend = document.getElementById('legend');
        for (var i in chart.chartData) {
            var row = chart.chartData[i];
            var color = chart.dataProvider[i].color;

            legend.innerHTML += '<div class="legend-item" id="legend-item-' + i + '" onclick="toggleSlice(' + i + ');" style="color: ' + "#777777" + ';"><div class="legend-marker" style="background: ' + color + '"></div>' + row.title+'</div>';
        }

如何避免循环？

非常感谢您的帮助！

发现问题，我把$.each函数去掉了
