Question

当我使用highstocks“Stockcharts”类型来显示具有正值和负值的时间序列时，系列存在但不可见。 API中有很多选项，我没有得到哪个可以显示正值和负值...有没有人遇到过同样的问题？

这是工作的基础：

<html>
    <head>

        // importing jquery, underscore.js, highstocks.js, moment.js
        <script>

        $(function(){
            dates = _.map([1,2,3,4,5,6], function(x){return moment().subtract(x, 'days').toDate();});
            values = [-1,1,0.1,0.2,-0.5,0.7]

            data = _.zip(dates, values);
            console.log(data);


            $('#graph').highcharts('StockChart',{
                title: {text: ''},
                series:[{
                    name: 'data',
                    data: data
                }]
            });

        })

        </script>
    </head>
    <body>
        <div id='graph'></div>
    </body>
</html>

修改

console.log(data);

的结果

# with moment().subtract(x, 'days').toDate().valueOf();
# or moment().subtract(x, 'days').valueOf();
Array[2], Array[2], Array[2], Array[2], Array[2], Array[2]]
   0: Array[2]
     0: 1446978478855
     1: -1
     length: 2
     __proto__: Array[0]
   1: Array[2]
     0: 1446892078856
     1: 1
     length: 2

# moment().subtract(x, 'days').toDate();
[Array[2], Array[2], Array[2], Array[2], Array[2], Array[2]]
  0: Array[2]

没有显示正值和负值的时间序列
