谷歌折线图：如何添加单位？ [英] Google Line Chart: How to add units?

问题描述

https://google-developers.appspot.com/图表/交互式/ docs / gallery / linechart＃示例

如何将单位添加到垂直轴，如$或€？在这个例子中，它应该是1.200 $，1.000 $，800 $，600 $和400 $。

How can I add units to the vertical axis like "$" or "€"? In the example, it should be 1.200 $, 1.000 $, 800 $, 600 $ and 400 $.

只要像这样添加'$'就行不通了： / p>

Just adding '$' like this doesn't work:

var data = google.visualization.arrayToDataTable([
      ['Year', 'Sales', 'Expenses'],
      ['2004',  1000 '$',      400],
      ['2005',  1170 '$',      460],
      ['2006',  660 '$',       1120],
      ['2007',  1030 '$',      540]
    ]);

我知道，这是一个糟糕的例子，因为销售没有任何单位，但它只是一个例子。

I know, it's a bad example as sales doesn't have any unit, but it's just an example.

推荐答案

您需要为您的图表选项添加一个格式标记，如下所示：

You need to add a format tag to your graph options as follows:

var options = {
    vAxis: {format:'# $'}
};
