具有分组数据的 Kendo 条形图，带有一个列表和基于不同列表的行

Question

我有一个剑道图表，其中我有从一月到六月的数据，其中有多个位置。例如，Jan 使用 A,B,Total 作为位置，Feb 使用 A,B,Total。现在我必须显示带有位置的条形图和总计的折线图。为了显示条形图，我们必须按位置分组，因此对于线也显示所有位置。你能帮我解决这个问题吗？我必须绘制没有位置的折线图，它应该像每个月一样。

@(Html.Kendo().Chart(Model.CertifiedIronProductionReports)

                                )
                                .ChartArea(chartArea => chartArea

Answer 1

如果您将每个月除一个条目之外的所有条目的总计更改为 null，则不会显示额外的行：

[
 {"lstTotal":null,"Location":"Tomball","IronCount":383,"Month":"Jan-2015","Total":null},
 {"lstTotal":null,"Location":"Average","IronCount":413,"Month":"Jan-2015","Total":null},
 {"lstTotal":null,"Location":"Grand Junction","IronCount":443,"Month":"Jan-2015","Total":null},
 {"lstTotal":null,"Location":"Total","IronCount":0,"Month":"Jan-2015","Total":826},
 {"lstTotal":null,"Location":"Tomball","IronCount":180,"Month":"Feb-2015","Total":null},
 {"lstTotal":null,"Location":"Average","IronCount":280,"Month":"Feb-2015","Total":null},{"lstTotal":null,"Location":"Grand Junction","IronCount":381,"Month":"Feb-2015","Total":null},
 {"lstTotal":null,"Location":"Total","IronCount":0,"Month":"Feb-2015","Total":561}
]

var dsCertpData = new kendo.data.DataSource({
    data: certData,
    group: {
        field: "Location",
    },
    sort:{       
        field :"Month",
        dir:"asc"
    }
});  

$("#chart1").kendoChart({
        dataSource: dsCertpData,
        legend: {
          position: "top",
          visible: true,
        },
        seriesColors: ["#00B0F0", "#E29B2C","#A05FCF","#3F890D"],
        series: [
          {
            type: "column",
            categoryField: "Month",
            field:"IronCount",
            stack: true
          },
          {
            type: "line",
            categoryField: "Month",
            field:"Total",
            visibleInLegend: false,
          }        
        ],
        tooltip: {
            visible: true,
            template: "${series.name} : ${value}"
        }
    });

注意：您当前正在将月份排序为字符串，因此 Feb 按字母顺序排在 Jan 之前。您需要将架构设置为使用实际日期字段来正确排序。
