在 Google 图表中显示 X 轴标题

Hum*_*mty 5 javascript android google-visualization column-chart

我想在 Android Web 视图中显示柱形图的 x 轴标题google charts。我试图显示 x 轴标题，如下Year所示

var data = google.visualization.arrayToDataTable([
    ['Year', 'Sales', 'Expenses', 'Profit'],
    ['2014', 1000, 400, 200],
    ['2015', 1170, 460, 250],
    ['2016', 660, 1120, 300],
    ['2017', 1030, 540, 350]

      title: 'Year'
    },
