Describe the bug A clear and concise description of what the bug is. I have noticed that on one of the charts the 0 point is showing up as -0.0. However sometimes it appears 0.0

Version of the card Version: 1.8.2

To Reproduce This is the configuration I used:

apexcharts_card_templates:
  all_series_no_legend_value:
    all_series_config:
      show:
        legend_value: false

- type: custom:apexcharts-card
    config_templates:
      - all_series_no_legend_value
    apex_config:
      chart:
        height: 300px
      yaxis:
        tickAmount: 5
    all_series_config:
      type: column
      data_generator: |
        let now = start.getTime();
        const data = JSON.parse(entity.attributes.data);
        return data.map((entry) => {
          const lNow = now;
          now += 30 * 60 * 1000;
          return [lNow, entry];
        });
    color_list: ['ROYALBLUE', 'ORANGE']
    graph_span: 24h
    stacked: true
    span:
      start: day
      offset: -1d
    series:
      - entity: sensor.energy_grid_usage
        name: Grid
      - entity: sensor.energy_solar_feedin

Sound like an issue on ApexCharts, not much I can do unfortunately.

Ok, thanks.

I think this is not -0.0. this is something -0.003. Real 0 position is a bit higher then "-0.0" I have same problem with stacked charts. I can manually set min/max with correct tickAmount. but this isn't good idea... we need something like "force zero tick".

Ran into the same issue. It helps to set forceNiceScale: true in y-axis through apex_config.

i.e. in the OP:

   apex_config:
      yaxis:
        tickAmount: 5
        forceNiceScale: true
