javascript - 更改谷歌图表列位置的问题

Question

我正在使用运行良好的谷歌图表，但我想更改列位置我的谷歌图表代码如下

google.charts.load('current', {'packages':['line']});
google.setOnLoadCallback(function() { drawLineChart(rows_arr); });

function drawLineChart(rows) {
        var res = JSON.parse('['+rows+']');
        const monthNames = ["January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December"
        ];

        const d = new Date();
        //debugger;
        var data = new google.visualization.DataTable();
        data.addColumn('number', monthNames[d.getMonth()]);
        data.addColumn('number', d.getUTCFullYear());
        data.addColumn('number', d.getUTCFullYear()-1);

        //console.log(rows);
        var date = new Date();
        var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
        var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);
        //debugger;
        data.addRows(res);
        var options = {
            chart: {
                title: '',
                subtitle: ''
            },
            axes: {
                x: {
                    0: {side: 'top'}
                }
            }
        };
        var chart = new google.charts.Line(document.getElementById('linechart_material'));
        chart.draw(data, google.charts.Line.convertOptions(options));       
    }

我的图表如下图所示 我想更改 2020 年和 2021 年的位置 我想将其显示在图表下方

有人可以帮我吗？
