Apexcharts - yaxis under config?

Hi all
I see many posts where they set yaxis configuration options under the “apex_config:” section. But the apexcharts site has yaxis as a primary indent (or whatever you call it when it isn’t indented under something). I have played with both but can’t figure out which should be used. If under apex_config, I can’t get things like decimals to work. But if I use it as a primary, then colour options don’t work. And I can’t use both.
Any advise on how to get colour and config options to work?
And please don’t just paste the apex site code. I have spend almost an hour and haven’t found the solution yet (he says knowing the first post will just be this).
Thanks

Nevermind. Just found a post that has it.
I need to add another apex_config under the yaxis - mentioning in case it helps someone else
