Column chart : custom the space between bars

Is your feature request related to a problem? Please describe. I’m frustrated because I don’t find the solution to manage easily the space between the bars.

Describe the solution you’d like A property to change the scale of x/y axes. I would like to make thin & tight bars :

Describe alternatives you’ve considered I tried to change the plotOptions > bar > columnWidth property, testing with stroke property too, change the grid parameters…

Additional context Code :

var totalChart = new ApexCharts(document.querySelector("#totalChart"), {
    series: [{
      name: 'Contrats',
      data: $('#totalChart').data('stats').split(',')
    }],
    chart: {
      type: 'bar',
      height: '170px',
      toolbar: { show: false },
      foreColor: '#657a8e',
    },
    plotOptions: {
      bar: {
        horizontal: false,
        columnWidth: '20%',
        distributed: true,
        colors: {
          backgroundBarColors: ['#F2F4F6']
        },
      }
    },
    legend: { show: false },
    xaxis: {
      axisBorder: { show: false },
      axisTicks: { show: false },
      categories: [
        'Cadre', 'MPDV', 'Groupement', 'Indirect'
      ],
      labels: {
        style: {
          fontSize: '12px'
        }
      }
    },
    yaxis: { show: false },
    colors: ['#007BFF'],
    grid: {
      show: false,
    },
    tooltip: {
      y: {
        formatter: function (val) {
          return val;
        }
      }
    }
  });
