小编ket*_*hyn的帖子

我在bitbucket有回购.它有2个分支master和Branch9_Artiflex但是当我通过源代码树(源树中的克隆克隆)将这个repo克隆到我的本地repo时,我只能看到master分支.

在我的本地计算机上创建新分支Branch9_Artiflex并从远程Branch9_Artiflex中提取所有数据不起作用,因为它们具有不同的提交历史记录

源树

但我的远程仓库有2个分支机构

实体类

顾客

       @Entity
        @Table(name="Custumer")
        public class Custumer implements Serializable {

            @Id
            @GeneratedValue(strategy = GenerationType.IDENTITY)
            @Column(name="id")
            private Long id;
            @Column(name="name",unique = true)
            private String name;
            @Column(name="Email",unique = true)
            private String Email;
            @Column(name = "Coins")
            private Double coins;

            @ManyToMany(fetch = FetchType.EAGER,cascade = CascadeType.ALL)

            private List<ShippingAdress> shippingAdress = new ArrayList<ShippingAdress>();


            @OneToMany( fetch = FetchType.EAGER, mappedBy = "custumer", cascade = CascadeType.ALL,orphanRemoval = true)

            private List<Order> orders= new LinkedList<Order>();

我有以下绘制条形图的脚本，我想在特定的 y 点上添加水平线。我正在尝试以下示例链接，我只是替换了 Chart.types.Line.extend，Chart.types.Bar.extend 但结果我得到了can not read property extend of undefined 所以有人可以帮助正确地在链接中实施上述示例或建议另一个决定

我的源代码没有水平线

  var ctx = document.getElementById("myChart");
        var myChart = new Chart(ctx, {
            type: 'bar',
            data: {
                labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
                datasets: [{
                    label: '# of Votes',
                    data: [12, 19, 3, 5, 2, 3],
                    backgroundColor: [
                        'rgba(255, 99, 132, 0.2)',
                        'rgba(54, 162, 235, 0.2)',
                        'rgba(255, 206, 86, 0.2)',

                        'rgba(153, 102, 255, 0.2)',
                        'rgba(255, 159, 64, 0.2)'
                    ],
