在这个小提琴中：

系列标签未正确显示。如果将鼠标悬停在数据点上，则x数据点将以毫秒显示为时间。

            serie[0].data.push({

        options.title.text = item.header;
        options.series = serie;
        $('#' + name).highcharts($.extend({}, options));
    });


});

如果我使用线图http://jsfiddle.net/LLExL/5123/，则显示日期。

如何在格式为dd/mm/yyyy hh:mm:ss的悬停时显示x轴值？

可以重命名弹出的x和y标签吗？

Answer 1

您可以使用工具提示格式化程序选项和Highcharts.dateFormat格式化您的需求。

tooltip: {
    formatter: function () {
        return 'x: ' + Highcharts.dateFormat('%d/%m/%Y %H:%M:%S', this.x) + '<br>' + 'y: ' + this.y;
    }
},
