如何创建一个函数以将月份作为 Jan、feb .. 显示在剑道图表 x 轴中。

var internetUsers = [ {
                            "Month": "1",
                            "year": "2010",
                            "value": 1
                        }, {
                            "Month": "2",
                            "year": "2010",
                            "value": 2
                        }, {
                            "Month": "3",
                            "year": "2010",
                            "value": 3
                        }, {
                            "Month": "4",
                            "year": "2010",
                            "value": 4

                        }, {
                            "Month": "5",
                            "year": "2010",

您可以使用 kendoui 的时间格式功能：

kendo.toString(new Date(2000, value, 1), "MMMM"); // if value = 9, it would output September

查看 kendoui 的日期格式页面。这是非常有帮助的。 http://docs.telerik.com/kendo-ui/getting-started/framework/globalization/dateformatting

首先添加一个数组来保存月份名称，如下所示：

var monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug"];

然后修改 categoryAxis 以使用这个数组

categoryAxis: {
    field: "Month",
    labels: {
        template: "#=monthNames[value - 1]#"
    },
},
