我很难在右侧获得垂直轴，我读了this帖子，但它是在5年前，并没有找到垂直图形方向。我也无法在图表的左侧和右侧显示垂直轴。
我希望有一种比制作假列更好的方法....

通常，您可以使用targetAxisIndex将轴移动到右侧，
但这似乎不适用于 - ＆gt; orientation: 'vertical'
虽然不理想，但您可以在图表的'ready'事件中手动移动轴...
请参阅以下工作代码段...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data1 = new google.visualization.DataTable();
data1.addColumn('number', 'x');
data1.addColumn('number', 'y1');
data1.addRows([
[0.005, 3],
[0.006, 6],
[0.007, 5],
[0.008, 8],
[0.009, 2],
[0.010, 5],
[0.011, 5],
[0.012, 4],
[0.013, 8]
]);
var data2 = new google.visualization.DataTable();
data2.addColumn('number', 'x');
data2.addColumn('number', 'y2');
data2.addRows([
[0.016, 5],
[0.017, 1],
[0.018, 3],
[0.019, 9],
[0.020, 4],
[0.021, 5],
[0.022, 7],
[0.023, 7],
[0.024, 3]
]);
var joinedData = google.visualization.data.join(data1, data2, 'full',
[[0, 0]], [1], [1]);
var options = {
title: 'playground',

label.setAttribute('x', xCoord);
} else if ((label.getAttribute('text-anchor') === 'middle') && (label.hasAttribute('transform'))) {

尝试将此添加到您的选项中：
series: {
0: { targetAxisIndex: 1, },
1: { targetAxisIndex: 1, },
}
这意味着你的系列都应该使用右侧轴。
