Chart for switch item only works for dynamic period

Switch items can be showed on a chart if you begin with the item definition analyze possibility and then save the chart. In the yaml code there is a markArea section that does the trick.

You can then customize the design or code.

The chart is saved with chart type ‘Dynamic period’. The code for my chart is:

config:
  label: Garagepoort
  period: W
slots:
  grid:
    - component: oh-chart-grid
      config: {}
  xAxis:
    - component: oh-time-axis
      config:
        gridIndex: 0
  yAxis:
    - component: oh-value-axis
      config:
        gridIndex: 0
  series:
    - component: oh-time-series
      config:
        gridIndex: 0
        xAxisIndex: 0
        yAxisIndex: 0
        type: line
      slots:
        markArea:
          - component: oh-mark-area
            config:
              item: Garagepoort
              name: Garagepoort

I would like to see the chart in a weekly mode, starting on Monday. This doesn’t work: nothing is visible (well, sometimes there is something to see, but it is not the actual situation). And on the X-axis there are no time values.

The only difference in the yaml code is at the beginning:

config:
  label: Garagepoort
  chartType: isoWeek

Is there a reason for this? Is there a workaround?

Using OH 4.1.1 with Openhabian on a Raspberry pi 3B.

Sounds like this is probably worth a bug report.
