Jquery浮动图表标签未显示

所以我正在学习flot图表，但在使用选项时，我很难显示标签或图例。某些选项会起作用（比如线条的填充和fillColor），但其他选项不行把头撞在桌子上

出于某种原因，它根本没有出现在jsfiddle中，但它出现在我的web应用程序中。

    var date = new Date(); //2015
    var date1 = date.setDate(date.getDate());

    var date3 = new Date(date.getFullYear() - 2, date.getMonth() - 5, date.getDate() - 6);
    dataTime = [
        [date1, 1],
        [date2, 3],
