amcharts简单封装

只是简单是封装了一下，目前只能输出线图（折现，圆滑线等），柱状图。

代码如下：

;!function(win,$,AC,undefined){
    var DDcharts = function(o){
        this.o = $.extend(true,{},this.default_o,o);
        if(this.o.type == 'serial'){
            this.chart = this.AmSerialChart();
            this.setCateGoryAxis().setValueAxis().setChartCursor().setAmLegend();
        }
    };

    DDcharts.prototype = {
        default_o:{
            type:'serial', // 类型：折线、饼图等
            dataProvider:{}, // 数据对象
            categoryField:'date',
            autoMargins:true,
            marginTop:0,
            marginRight:0,
            marginBottom:0,
            marginLeft:0,
            startDuration:1, // 动画时间
            write2where:'ddchart',
            // 横轴
            categoryAxis:{
                parseDates:true,
                minPeriod:'DD', // 最小时间：fff - milliseconds, ss - seconds, mm - minutes, hh - hours, DD - days, MM - months, YYYY - years.
                inside:false,
                fillAlpha:0.1, // 间隔区域透不明度
                fillColor:'#cccccc', // 间隔区域填充颜色
                labelRotation:0, // 刻度旋转角度
                startOnAxis:0
            },
            // 纵轴
            valueAxis:{
                title:'', // 轴名称
                axisAlpha:0,
                dashLength:5
            },
            line:{
                type:'line', // Possible values are: "line", "column", "step", "smoothedLine", "candlestick", "ohlc". XY and Radar charts can only display "line" type graphs.
                valueField:'value',
                hideBulletsCount:50
            }
        },
        AmSerialChart:function(){
            var chart = new AC.AmSerialChart();
            chart.dataProvider = this.o.dataProvider;
            chart.categoryField = this.o.categoryField;
            chart.autoMargins = this.o.autoMargins;
            chart.startDuration = this.o.startDuration;
            if(this.o.autoMargins == false){
                chart.marginTop= this.o.marginTop;
                chart.marginRight= this.o.marginRight;
                chart.marginBottom= this.o.marginBottom;
                chart.marginLeft= this.o.marginLeft;
            }
            return chart;
        },
        // 设置横轴
        setCateGoryAxis:function(){
            var categoryAxis = this.chart.categoryAxis;
            categoryAxis.parseDates = this.o.categoryAxis.parseDates; // as our data is date-based, we set parseDates to true
            categoryAxis.minPeriod = this.o.categoryAxis.minPeriod; // our data is daily, so we set minPeriod to DD

            return this;
        },
        // 添加鼠标滑过时的效果
        setChartCursor:function(){
            var chartCursor = new AC.ChartCursor();
            this.chart.addChartCursor(chartCursor);
            return this;
        },
        // LEGEND
        setAmLegend:function(){
            var legend = new AC.AmLegend();
            legend.markerType = "square"; // Possible values are: "square", "circle", "line", "dashedLine", "triangleUp", "triangleDown", "bubble", "none".
            this.chart.addLegend(legend);
        },
        // 增加折线
        addLine:function(valueField,type,title){
            var graph = new AC.AmGraph();
            graph.type = type || this.o.line.type;
            if(graph.type == 'column'){
                graph.fillAlphas = 0.8;
            }else{
                graph.bullet = "round";
            }
            graph.valueField = valueField || this.o.line.valueField;

            this.chart.addGraph(graph);
            return this;
        },

        write:function(write2where){
            this.chart.write(write2where || this.o.write2where);
        }
    }

    win.DDcharts = DDcharts;

}(this,jQuery,AmCharts);

使用实例（ddcharts.js为上述封装代码）：
