jquery - 隐藏折线图中的零值 Kendo ui

Question

是否有办法隐藏折线图中零 (0) 值的数据点？我目前正在使用折线图(Kendo)，似乎找不到一种简单的方法来做到这一点。基本上，一条线显示在图表上的 0 值处，我宁愿根本不显示该线。数据绑定(bind)线结束值之一为零(我必须删除它)。示例数据如 [30,50,40 ,75,0]

这里我提供了 html 代码

 $.ajax({
                type: "POST",
                contentType: "application/json;charset=utf-8",
                url: "dataVizWebService.asmx/GetSellInOfficeTrends",
                dataType: "json",
                success: function (data) {

                    $("#chart").kendoChart({
                        dataSource: {
                            data: data.d,
                            value: "#={0}>0"
                        },
                        legend: {
                            position: "bottom"
                        },
                        title: {
                            text: "Population"
                        },
                        series: [
                                    {
                                        type: "line",
                                        field: "Population2010",
                                        name: "Population2010",
                                        axis: "Year",
                                        color: "#4a7ebb"
                                    }, {
                                        type: "line",
                                        field: "Population2011",
                                        name: "Population2011",
                                        axis: "Year",
                                        color: "#be4b48"
                                    }, {
                                        type: "line",
                                        field: "Population2012",
                                        name: "Population2012",
                                        axis: "Year",
                                        color: "#98b954"
                                    }, {
                                        type: "line",
                                        field: "Population2013",
                                        name: "Population2013",
                                        axis: "Year",
                                        dashType: "dash",
                                        color: "#000000"
                                    }
                                    ],
                        valueAxis: [{
                            name: "Year",
                            title: { text: "Population in Millions" }
                        }],
                        categoryAxis: {
                            field: "Week",
                            majorTickType: "none",
                            labels: {
                                skip: 0
                            }
                        },
                        tooltip: {
                            visible: true
                        }
                    })
                }
            });

任何帮助将不胜感激。

Kendoui API 文档中存在缺失值属性。您可以使用这些属性并检查哪些对您有用。
