showing line chart vertical axis in another number

问题:

There is a solution, but you'll have to use an undocumented feature, which will be documented at some point. You'll need to make this call sometime before you draw your chart.

google.visualization.NumberFormat.useNativeCharactersIfAvailable(true);

This works with material charts prior to v46, and also in classic charts starting with v46. See this example: https://jsfiddle.net/dlaliberte/6k8vdgz7/

You may see some problems depending on what formatting options you also specify.
