                        ]);
                        newVisitors.push([

                options.series[0].data = allVisits;
                options.series[1].data = newVisitors;

                chart = new Highcharts.Chart(options);
            });

        });

    </script>

上面是jquery插件'highcharts'的示例代码，我试图从json文件中获取数据，如果json字符串为：          {             名称：'allVisits'，             数据：[1,0,4]          }，{             名称：'newVisits'，             数据：[5,7,3]          }

示例文件是从'tsv'文件获取数据，所以我试图从json文件中获取数据。
