Javascript 图表标题重叠

我有一张这样的图表： 函数构造函数PieChartData、chartDiv、showLegend、legendPos、color、， 显示值，图表底部{

showLegend = typeof showLegend !== 'undefined' ? showLegend : true;
legendPos = typeof legendPos !== 'undefined' ? legendPos : "right";

var pieChart = new AmCharts.AmPieChart();
pieChart.dataProvider = chartData;
pieChart.titleField = "title";
pieChart.valueField = "value";
pieChart.outlineColor = "#FFFFFF";
pieChart.minRadius = 150;

if (chartBottom != 0) {
    pieChart.marginTop = chartBottom;
}
pieChart.outlineAlpha = 0.8;
pieChart.outlineThickness = 2;
if (!showValue) {
    pieChart.labelText = "[[title]]";
    pieChart.labelRadius = 50;
    pieChart.pullOutRadius = 70;
}


// show different color
if (color != null) {

    for ( var i = 0; i < chartData.length; i++) {
        var objectTitle = chartData[i].title;
        if (objectTitle == "nötr") {
            colorList[i] = color[0];
        } else if (objectTitle == "pozitif") {
            colorList[i] = color[2];
        } else if (objectTitle == "soru") {

但当你点击其中一个标题时，它会上升并与上面的标题重叠。如何避免这种重叠

提前购买thanx。
