Apexcharts question: scale y axis based on brush selection

[lennon101]

Has anyone been able to figure out how to scale the y axis based on the brush selection? I have a graph that spans across 3 days with a brush selection that defaults to 12 hours. The plot shows the total daily rain (reset to 0.0mm at midnight) and the current rain rate (in mm/hr). Currently the both y-axis (left and right side) are scaled to the largest value in the 3 day span. I want both y-axis to independently scale and update as I move the brush selection.

You can see in my code below I have tried several things (unsuccessfully) to force the auto-scale of the y-axis by setting the in-brush config and the apex_config using (neither of which have worked):

brush:
  selection_span: 12hrs
  apex_config:
    enabled: true
    autoScaleYaxis: true
apex_config:
  brush:
    autoScaleYaxis: true

Yaml config:

type: custom:apexcharts-card
graph_span: 3days
yaxis:
  - id: first
  - id: second
    opposite: true
header:
  show: true
  title: Daily Total Rain
  show_states: true
  colorize_states: true
experimental:
  brush: true
brush:
  selection_span: 12hrs
  apex_config:
    enabled: true
    autoScaleYaxis: true
apex_config:
  brush:
    autoScaleYaxis: true
series:
  - entity: sensor.gw1100c_v2_2_1_daily_rain_rate
    type: line
    color: aqua
    yaxis_id: first
    stroke_width: 3
    curve: smooth
    show:
      in_brush: false
      in_chart: true
  - entity: sensor.gw1100c_v2_2_1_rain_rate
    type: line
    name: Rain Rate
    yaxis_id: second
    stroke_width: 2
    curve: stepline
all_series_config:
  show:
    in_brush: true
  opacity: 1
  float_precision: 2

It does the exact same thing to me too, I’ve tried everything, but the y-scale is set to the maximum value found in the contents of the graph_span: range and not as it should be in the selection_span: range.
The original library works fine:

I am attaching some screenshots, as per my previous post:
… is it a bug to report or is it a problem with my code?

Hi all,
Anyone found a solution already for this issue?
I have a graph that once in a few days shows some bursts but for the rest very small values. And the beauty about the brush in the original Apexchart.js is that it zooms in the y-axis automatically
