我正在使用这段代码生成图表。我必须将数据推入一个函数的数组中。然后我将它传递给绘图函数。但是当我这样做的时候，我得到了这个错误Data column(s) for axis #0 cannot be of type string。知道是什么问题吗？

function setData(records) {
$("#result").show();

var chartData = [];

    chartData.push(['A', 'B', 'C', 'D']);

    // A SIMPLE FOR EACH LOOP STARTS
    chartData.push([
        X,Y,P,Q
    ]);
    //FOR EACH ENDS
drawVisualization(chartData);
}

google.charts.load('current', { 'packages': ['corechart'] });

function drawVisualization(chartData) {

var data = google.visualization.arrayToDataTable([
    chartData
]);

var options = {
    title: 'Monthly Coffee Production by Country',
    vAxis: { title: 'Measure' },
    hAxis: { title: Row },
    seriesType: 'bars',
    series: { 5: { type: 'line' } }
};

var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
