Issue: Monthly chart compressed horizontally for current month

[mafieu86]

Description
The ApexCharts card displaying monthly consumption for the current month (offset = 0) shows all bars compressed/clustered on the right side of the chart instead of being evenly distributed across the entire month width.

Configuration

• Card: apexcharts-card with state-switch (key "0.0" for current month)
• Type: Stacked column chart (HP/HC)
• Span: start: month, offset: +0month
• Graph span: 32d (used to fix another bug)
• Group by: duration: 1d, func: delta, fill: zero

xaxis configuration

xaxis:
  type: datetime
  tickAmount: 31
  tickPlacement: "on"
  labels:
    formatter: |
      EVAL:(val) => {
        return new Date(val).getDate();
      }
    rotate: -90
    rotateAlways: true
    hideOverlappingLabels: false
    showDuplicates: false
    trim: false
    style:
      fontSize: 8px
  axisBorder:
    show: false
  axisTicks:
    show: true

Observed behavior

• Data appears to be present (all HP/HC stacked bars are visible)
• X-axis labels (day numbers) are visible but compressed
• All bars are grouped in approximately 20% of the chart width (right side)
• The rest of the chart is empty on the left

Tested without success
✗ Changed func: diff to func: delta
✗ Changed series entities (sensor.energie_reseau_serveurs_mois_hp → sensor.energie_reseau_serveurs_jour_hp)
✗ Removed plotOptions and dataLabels
✗ Used graph_span: 1month instead of 32d
✗ Removed custom tooltip

Question
Why doesn't ApexCharts distribute the daily bars evenly across the entire month width when the data seems to be present?

Thank you very much

It is a known issue but there is one error in your statement/assumption, the data is not present for the current (!) month, you only have till 2nd Oct. Nevertheless, it would be nice if the distribution takes the span>end: month into account which it does not. The underlying library has the same 'issue' so not sure if this can see a solution here, other than maybe pre-filling 'the month with fake values ...but then 'which' values as 0 is not good as well in many situations
