我在我的应用程序中使用条形图（amcharts），我需要包含该条形图的图例。所以，我为条形脚本添加了以下脚本，

legend = new AmCharts.AmLegend();
legend.position = "bottom";
legend.align = "center";
legend.markerType = "square";
legend.valueText = "";
chartx.addLegend(legend);

但是，条形图应该显示图例？如何在我的条形图应用程序中添加图例。

谁能尽快给我这个问题的解决方案？

        <script type="text/javascript">
            var chart;

            var chartData = [{
                year: 2005,
                income: 23.5
            }, {
                year: 2006,
                income: 26.2
            }, {
                year: 2007,
                income: 30.1
            }, {

            AmCharts.ready(function () {

                // this single line makes the chart a bar chart,
                // try to set it to false - your bars will turn to columns
                chart.rotate = true;
                // the following two lines makes chart 3D
                chart.depth3D = 20;
                chart.angle = 30;

                // AXES

                graph.bullet = "round";
                chart.addGraph(graph);


                                // LEGEND
