Add suffix to v-axis google chart

Question

I have a Google Line Chart showing temperature over time. I can't figure out how to add a suffix to the v-axis values. I would like for the values (for example 10 on the v-axis) to say 10˚C.

Does it exist a:

var option = {
vAxis: {}
}

for adding a suffix to values? Any help is greatly appreciated.

Answer 1

This solution worked! :)

var option = {
  vAxis: {
     format: '#,##0˚C'
  }
}
