I have a apexcharts-card to show some forecast-data. But if I use show_states in the header it shows the last state. I want to show the first state (todays value). Is this possible ?

type: custom:apexcharts-card
experimental:
  color_threshold: true
  brush: true # This is required
header:
  show: true
  show_states: true
