[6.0.0] Can't change y-axis units with StackDriver DS

Good day everyone,

I’m testing StackDriver datasource in Grafana 6.0.0 (didn’t use it before) and it seems that Y axis units are pre-set depending on the selected SD metrics and there is no way to change it.

For example, I would like count the number of online VMs in my GCE. But no matter what I do, Y axis keeps showing “seconds”, even if I set Aggregation to “count” the Y-axes are still formatted as time - I can’t change it via Visualization tab and even if I alter panel JSON, it gets reset back to “s”.

Is there a bug here or am I missing something?
