以编程方式添加 plotbands kendo 图表

Question

kendo 版本 2015.1.429

我不明白为什么这不起作用。我已经和它战斗了几个小时但无济于事。我已经尝试了轴名称等的各种变体。

有什么想法吗？

对于分类图表类型，我们应该使用 categoryAxis 和 valueAxis plotBands。

<script>
      var stats = [
                    { value: 48, date: new Date("2014/01/01") },
                    { value: 50, date: new Date("2014/01/02") },
                    { value: 55, date: new Date("2014/01/03") },
                    { value: 35, date: new Date("2014/01/04") },
                    { value: 30, date: new Date("2014/01/05") },
                    { value: 30, date: new Date("2014/01/20") },
                    { value: 50, date: new Date("2014/01/21") },
                    { value: 45, date: new Date("2014/01/22") },
                    { value: 40, date: new Date("2014/01/23") },
                    { value: 35, date: new Date("2014/01/24") },
                    { value: 40, date: new Date("2014/01/25") },
                    { value: 42, date: new Date("2014/01/26") },
                    { value: 40, date: new Date("2014/01/27") },
                    { value: 35, date: new Date("2014/01/28") },
                    { value: 43, date: new Date("2014/01/29") },
                    { value: 38, date: new Date("2014/01/30") },
                    { value: 30, date: new Date("2014/01/31") }                    
                ];


      $("#chart").kendoChart({
        dataSource: {
            data: stats
        },
        series: [{
            type: "column",
            aggregate: "avg",
            field: "value",
            categoryField: "date"
        }],
        categoryAxis: {
            type: "date",
            majorGridLines: {
                visible: false
            }
        },
        valueAxis: {
            line: {
                visible: false
            }
        } 
      });

      $(function(){
        var chart = $("#chart").data("kendoChart");
        var options = {};         
        var fromDate = new Date("2014/01/15");
        var toDate = new Date("2014/01/20");;        
        options["categoryAxis"] = { plotBands: [{ from: fromDate, to: toDate, color: "green", opacity: 0.3 }] };  
        options["valueAxis"] = { plotBands: [{ from: 10, to: 20, color: "yellow", opacity: 0.3 }] };
        chart.setOptions(options);        
    });
</script>

虽然对于散点图类型，我们应该使用 xAxis 和 yAxis plotBands

<script>
    function createChart() {
            $("#chart").kendoChart({
                title: {
                    text: "Rainfall - Wind Speed"
                },
                legend: {
                    position: "bottom"
                },
                seriesDefaults: {
                    type: "scatter"
                },
                series: [{
                    name: "January 2008",
                    data: [

                },{

                }],
                xAxis: {
