[help] How to not display values after the current time

[deltacle]

Hello

I'm using this simple graph :

type: custom:apexcharts-card
graph_span: 24h
span:
  start: day
now:
  show: true
series:
  - entity: sensor.temperature_garage_temperature
    name: Temp

How can I display no value, or zero value after the now (the current time) ?
Currently, the graph display the last value.

Thanks a lot for your help

I found the response.
In the entity, set this attribute:
extend_to: now
