                            ['Firefox',   25],
                            ['IE',       75],

                        ]
                    }]
                });
            });
                
        </script>
        
    </head>
    <body>
        
        <!-- 3. Add the container -->
        <div id="container" style="width: 800px; height: 400px; margin: 0 auto"></div>
        
                
    </body>
</html>

在这个位置data: [
['Firefox', 25],
['IE', 75],
]
填25与75就不能把百分比显示出来
而25与23就可以，请问这是为什么呢？

呃~·看不出所以然，具体得看这个方法的源码~·
------解决方案--------------------
呵呵图的问题一般都挺复杂的就算扒拉源码也得看一阵子何况还是jquery 等高人吧~~~

下面代码能运行，75后面有逗号也可以，但在其它浏览器可能不允许这样（比如FF），所以最好规范些
