flot柱狀圖上顯示數字

使用flot的插件jquery_flot_barnumbers.js，

bars: {
            show: true,
            fill: 0.8,
            align: "center",
            barWidth: 1,
            lineWidth: 0,
            numbers: {

	show : boolean,
            xAlign : null or function like function (x) {return x + 0.5;}, (if null, the text is in the middle,偏移x)
            yAlign : null or function like function (y) {return y + 0.5;}, (if null, the text is in the middle,偏移y)
            font : {size : number, style : string, weight : string, family : string, color : string},
            rotate : number (傾斜度)

            }
        },
