我试图在应用程序中绘制图表，我每个月都会显示数据，并希望在x轴上添加标签以表示年份，但是当我尝试自动添加标签时添加年份和月份使应用程序的外观变得混乱。

有人可以建议在图表上使用年份标签（2010：2014）吗？
答案 0 :(得分：0)
您可能需要循环浏览数据以根据需要进行更改：
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;
}
