Apex chart Y-axis not scaling as defined

Configuration Frontend

On my Y-axis, left, I expect there to be a scale from 17.0 to 23.0 with steps of 0.5. However this is not happening and I do not understand why.

Mine works, and I think I went through the same process as you and got it by putting these settings in a general apex_config (ie. no indentation) rather than under the yaxis.

type: custom:apexcharts-card
apex_config:
  yaxis:
    opposite: true
    min: 17.0
    stepSize: 0.5
    max: 23.0

thanks
close, but…

other way round,
I want the step size 0.5 on the left with the min,max…and on the right no minimax no step, plotting only LWT

The challenge is that if the parameters can be managed on different levels, overwriting/ruling them with apx_config not always works.
Try this

  - id: kitchen
    opposite: false
    show: false
    max: 23
    min: 17
    apex_config:
      stepSize: 0.5

Side note: not sure why you defined 3 axis with the same settings, one would be enough

because if I omit any of the “- I’d:” attributes, I get an error for each one, so all four must be defined !

/// apexcharts-card version 2.1.2 /
// yaxis_id: lounge doesn't exist.

If I add lounge but omit kitchen then the above area disappears but it’s replaced by kitchen doesn’t exist error, and so on.
All four must be defined

??

your solution makes no difference sorry thanks for trying

You should refer all 3 series to the single y-axis…and not 3 series to 3 y-axis with the same setup (makes no sense)
and my solution does work but anyhow… you have to play around

Doesn’t work for me
Maybe it’s something else

what do you mean

“refer all 3 series to the single y-axis”.

how? because I thought that’s what I’m doing with the three IDs under the y-axis attribute
