Question

我正在使用Kendo创建一个图表并遇到了问题。

我收到大量数据并将其传递到图表中，数据有日期和值，我的js看起来像这样：

chart.kendoChart({
                 title: {
                     text: "title"
                 },
                 seriesDefaults: {
                     type: "line"
                 },
                 dataSource: {
                     data: []
                 },
                 series: [{
                     name: "Value",
                     field: "value"
                 }]
                 categoryAxis: [{
                     type: "date",
                     field: "date",
                     baseUnit: "months",
                     min: "2013-07-22T00:00:00",
                     max: "2014-07-22T00:00:00"
                 }]
             });

问题是，如果没有返回数据（即上面的空数组），我仍然希望在底部看到月份日期标签，但是那里没有任何内容（仍然有默认值标签） y轴）。

我查看了Kendo文档，但在stackoverflow上找不到任何内容，也没有任何类似的问题。有人可以帮忙吗？如果有任何我需要澄清/提供的内容，请在评论中告诉我。感谢。

在没有数据的月份内使用空值填充数据可以解决您的问题。

请参阅此Fiddle作为示例：

另见以下示例代码：

var _data=[{"weight":200,"createddate":"1/1/2014"},
       {"weight":200,"createddate":"2/1/2014"},
       {"weight":200,"createddate":"3/1/2014"},
       {"weight":149.91,"createddate":"4/1/2014"},
       {"weight":null,"createddate":"5/1/2014"},
       {"weight":null,"createddate":"6/1/2014"},
      {"weight":null,"createddate":"7/1/2014"},
      {"weight":null,"createddate":"8/1/2014"},
      {"weight":null,"createddate":"9/1/2014"},
      {"weight":null,"createddate":"10/1/2014"},
      {"weight":null,"createddate":"11/1/2014"},
      {"weight":null,"createddate":"12/1/2014"}]

        $("#kk").kendoChart({
            dataSource: {
                data:_data
            },
            seriesColors: ["Red"],                
            seriesDefaults: {
                type: "column",
            },
            series: [{
                name: "weight",
                field: "weight",
                categoryField: "createddate",
            }],
            categoryAxis: {
                type: "date",
                baseUnit: "months"
            }                        
        });

在剑道Dataviz中强制日期轴具有所有值
