extjs4.1中chart的bug
在点击右侧“图例"中的内容时，图形变化错误，例如：依次点击”男性“-”人数“-”男性“-”人数“就会发现图形和一开始不一样了,这个是我自己写的，大家可以用官方的demo测试，也是一样的有错误，希望ext官方尽快修改！！
Ext.onReady(function(){ var data = [{"户籍区划":"海南区","人数":97132,"男性":50839,"女性":46293},{"户籍区划":"乌达区","人数":133321,"男性":68023,"女性":65297},{"户籍区划":"海勃湾区","人数":191882,"男性":97115,"女性":94767}]; var fields = ["户籍区划","人数", "男性", "女性"]; var store = Ext.create('Ext.data.JsonStore', { fields: fields, data: data }); var chart = Ext.create('Ext.chart.Chart', { xtype: 'chart', animate: true, style: 'background:#fff', shadow: false, legend: { position: 'right' }, store: store, axes: [{ type: 'Numeric', position: 'left', fields: ["人数", "男性", "女性"], grid:true, minimum: 0 }, { type: 'Category', position: 'bottom', fields: ["户籍区划"] }], series: [ { "type":"line", "axis":"bottom", "highight":true, "xField":"户籍区划", "yField":"人数" }, { "type":"line", "axis":"bottom", "highight":true, "xField":"户籍区划", "yField":"男性" }, { "type":"line", "axis":"bottom", "highight":true, "xField":"户籍区划", "yField":"女性" } ] }); var win = Ext.create('Ext.panel.Panel', { width: 600, height: 400, minHeight: 400, minWidth: 550, hidden: false, maximizable: true, title: 'Bar Chart', renderTo: Ext.getBody(), layout: 'fit', items: chart });});
