How can I remove the horizontal lines of that chart & its axis lines (so that this looks much cleaner)

    this.chartOptions = {
      series: [
        {
          name: "distibuted",
          data: [21, 22,]
        }
      ],
      chart: {
        height: 350,
        type: "bar",
        events: {
          click: function(chart, w, e) {
            // console.log(chart, w, e)
          }
        }
      },
      colors: [
        "#008FFB",
        "#00E396",
      ],
      plotOptions: {
        bar: {
          columnWidth: "45%",
          distributed: true
        }
      },
      dataLabels: {
        enabled: false
      },
      legend: {
        show: false
      },
      xaxis: {
        categories: [
          ["John", "Doe"],
          ["Joe", "Smith"],
        ],
        labels: {
          style: {
            colors: [
              "#008FFB",
              "#00E396",
            ],
            fontSize: "12px"
          }
        }
      }
    };

& also how can I format the tooltip colors ?
