Apexcharts-card stacked area chart will not stack

Hi, I am new to apex charts-card, but it is doing all kinds of things for me that the default history graph card can't do. So that's great. But I have a weird issue with stacked area charts that I can't figure out.

I've created charts in the history graph card and in apex charts-card, using the same series and the same timespan.

As you can see, the apexcharts graph is not stacked.

What am I missing?

The YAML is:

type: custom:apexcharts-card
graph_span: 3h
stacked: true
grid_options:
  columns: full
series:
  - entity: sensor.curb_dqwvr8rf_c1
    type: area
  - entity: sensor.curb_dqwvr8rf_c6
    type: area
  - entity: sensor.curb_dqwvr8rf_c2
    type: area
  - entity: sensor.curb_dqwvr8rf_a3
    type: area
  - entity: sensor.curb_dqwvr8rf_b3
    type: area
  - entity: sensor.curb_dqwvr8rf_a4
    type: area
  - entity: sensor.curb_dqwvr8rf_b4
    type: area
  - entity: sensor.curb_dqwvr8rf_b5
    type: area
  - entity: sensor.curb_dqwvr8rf_c4
    type: area

try this:

apex_config:
chart:
stacked: true

Also there is a github-page for the card, as well as a dedicated Topic, where people “meet/follow” issues and requests
ApexCharts card - A highly customizable graph card .
Sometimes it’s easier to jump into this Topic, and “ Search in This Topic “

Thanks! I searched but did not see that Topic. I'll bookmark it.

Yeah, there are +100000 Topics in here :grinning_face_with_smiling_eyes:
