Google图表轴标签

Question

我正在尝试在一个应用程序中绘制一个图表，在该应用程序中，我逐月显示数据，并希望在x轴上添加标签来表示年份，但是当我尝试添加标签时，它会自动添加年份和月份，从而使应用程序的外观变得混乱。

         var e=new google.visualization.arrayToDataTable([
            ["Year",county_1,county_2,"National"],
            ["Jan-10",med_jan_10_1,med_jan_10_2,med_jan_10_3],
            ["Feb-10",med_feb_10_1,med_feb_10_2,med_feb_10_3],
            ["Mar-10",med_mar_10_1,med_mar_10_2,med_mar_10_3],
            ["Apr-10",med_apr_10_1,med_apr_10_2,med_apr_10_3],

          ]);

            var b={
              title:"House Price Index by County:",
              curveType:"function",
              is3D:true,
              legend:"top",
              width:600,
              height:250,
              hAxis: {textPosition: 'none' }};
            var d=new google.visualization.LineChart(document.getElementById("chart_div"));
            d.draw(e,b)
        }

有没有人能建议一种只在图表上标注年份(2010:2014)的方法？

您可能需要遍历数据以根据需要对其进行更改：

var exampleData = ["Jan-10",med_jan_10_1,med_jan_10_2,med_jan_10_3];
for (var i = 0; i < exampleData.length; i++) {
    var date = exampleData[i][0];
    var year = '20' + date.split('-')[1];
    exampleData[i][0] = year;
}
