Extjs 图表控件，可修改X轴与Y轴坐标

this.xAxisName = '区县名称';

this.yAxisName = '站点个数';

this.store = new Ext.data.ArrayStore({         fields: ['month', 'hits']     }),

this.analysisPanel = new Ext.chart.ColumnChart({

        store: this.store,

        yField: 'hits',

        title: '站点统计',

        url: '/JS/Ext3.2.0/resources/charts.swf',

        xField: 'month',        

　　　xAxis: new Ext.chart.CategoryAxis({

　　　}),        

　　　yAxis: new Ext.chart.NumericAxis({

            title: this.yAxisName

        }),        

　　   extraStyle: {

            xAxis: {labelRotation: -90  }        

　　　}

});

// 重新设定统计窗体的提交后的更新状态

 this.formPanel.form.submit({
        success: function(form, action) {
                this.parent.analysisPanel.setXAxis(new Ext.chart.CategoryAxis({

　　　　　　　　 // 读取服务器端的x轴名称
                         title: action.result.xAxisName
                 }));

                 this.parent.analysisPanel.setYAxis(new Ext.chart.NumericAxis({
                          title: action.result.yAxisName

                  this.parent.store.loadData(generateData(action.result.records));

                  this.parent.analysisPanel.refresh();
                  this.parent.analysisWinForm.hide();

// 将服务器端返回的数据放到store里面，可以弄一个Json store 来搞...
