Google 图表轴百分比

Google Charts Axis Percentage

https://jsfiddle.net/vko75dg4/

我想将数字作为百分比,但它对我不起作用。当您将鼠标悬停在图表上时,我还想去掉日期旁边的时间。

有什么想法吗?谢谢

阅读 Line Chart documentation 你可以知道你需要使用 chart.draw(data, google.charts.Line.convertOptions(options)); 来替换你的 chart.draw(data, options);

虽然使用 % 后缀会导致一些不需要的格式,它会将您的数据乘以 100,但您可以先将数据除以 100。
