Describe the bug If I enter a value for float_precision, the 5 values on the y-axis has the precision of the entity and not of the wanted floaat_precision.

Version of the card Version: 2.0.4

To Reproduce This is the configuration I used:

header:
  show: true
  title: Klimaanlage Stromverbrauch
  show_states: true
  colorize_states: true
series:
  - entity: sensor.klimaanlage_current_power
    type: line
    color: '#3b719c'
    float_precision: 0
    stroke_width: 2
    curve: stepline
    show:
      name_in_header: false

Screenshots

Expected behavior The amount of decimal places of the y-axis should be the float_precision-value.
