如何添加图例到剑道股票图表使用多个系列

我们有一个页面，其中有股票图表，除了股票图表，在同一个页面中，我们也有网格，也在Kendo StockChart图例中没有动态显示。所以我试过在代码中使用多个系列:但是，当运行此代码图例值重复时，如何解决此问题

$(document).ready(function () {
    var db = new kendo.data.DataSource({
        data : data,
        group: {
            field: "studentmarks"
        }
    });
    db.read();
    $("#Chart").kendoStockChart({
        theme     : $(document).data("kendoSkin") || "silver",
        dataSource: db,
        aggregate : [
            { field: "ID", aggregate: "aggregate", line: "line"}
        ],

        title         : {
            text: "CDR"
        },
        dateField     : "time",
        repeat        : false,
        legend        : {
            position: "right"
        },
        chartArea     : {
            background: ""
        },
        seriesDefaults: {
            type: "line", field: "ID"
