Question

我有一张JQuery邮票图表：

HTML

               <div class="col-md-6 col-sm-12">
                    <!-- BEGIN PORTLET-->

                xaxis: {

                colors: ["#e14e3d"],
                grid: {
                    tickColor: "#a8a3a3",
                    borderWidth: 0
                }
                });

                function statisticsUpdate() {
                plot_statistics.setData([getRandomData()]);
                plot_statistics.draw();
                setTimeout(statisticsUpdate, updateInterval);

                }

                statisticsUpdate();

                $('#load_statistics').bind("mouseleave", function () {
                    $("#tooltip").remove();
                });
            }

所以，我的问题是我想要显示几天而不是{1,2,3,4,5,6,7}。我试过这样做：

var Last_Week = [
                ["Sun", 3],
                ["Mon", 345],
                ["Tue", 34],
                ["Wed", 234],
                ["Thu, 435],
                ["Fri", 458],
                ["Sat", 879]
            ];

var This_Week = [
                ["Sun", 134],
                ["Mon", 789],
                ["Tue", 423],
                ["Wed", 416],
                ["Thu", 489],
                ["Fri", 157],
                ["Sat", 340]
            ];

但它告诉我这个：

它的意思是我错了。你能帮我吗？

Answer 1

不是为您的x轴（ticks: 11,）定义多个刻度，而是指定刻度线的array with the labels（并保留数据中的数字，这是must）：

ticks: [[1, "Sun"], [2, "Mon"], [3, "Tue"], ...]
