About the component of the legend above the echarts chart

can the legend component at the top of the chart be turned into a column chart? Or can I get its callback?

option = {
    title: {
        text: ""
    },
    tooltip: {
        trigger: "axis"
    },
    legend: {
        data:["","","","",""]
    },
    grid: {
        left: "3%",
        right: "4%",
        bottom: "3%",
        containLabel: true
    },
    toolbox: {
        feature: {
            saveAsImage: {}
        }
    },
    xAxis: {
        type: "category",
        boundaryGap: false,
        data: ["","","","","","",""]
    },
    yAxis: {
        type: "value"
    },
    series: [
        {
            name:"",
            type:"line",
            stack: "",
            data:[120, 132, 101, 134, 90, 230, 210]
        },
        {
            name:"",
            type:"line",
            stack: "",
            data:[220, 182, 191, 234, 290, 330, 310]
        },
        {
            name:"",
            type:"line",
            stack: "",
            data:[150, 232, 201, 154, 190, 330, 410]
        },
        {
            name:"",
            type:"line",
            stack: "",
            data:[320, 332, 301, 334, 390, 330, 320]
        },
        {
            name:"",
            type:"line",
            stack: "",
            data:[820, 932, 901, 934, 1290, 1330, 1320]
        }
    ]
};
