I want to show a Horizontal Bar Chart from ChartJS inside my Ion-Slide. My ion-slide is the container of my BarChart and has a fixed height. But I want to resize my ion-slide height depend on the count of my data. But because my ion-slide is an container with fixed height, it resizes the Chart.
My question:
How to set the height of the ion-slide depend of my data.length so the bar has always the same BarThickness and spacing and how to configure my ChartJS Bar?

My ChartJS code:

var myChart = new Chart(ctx, {

  type: "horizontalBar",

  data: {

    labels: chartLabels,

    datasets: [

      {

        label: label1,

        backgroundColor: "green",

        data: erholungsValues

      },

      {

        label: label2,

        backgroundColor: "red",

        data: beanspruchungsValues

      }

    ]

  },

  options: {

    barValueSpacing: 20,

    scales: {

        yAxes: [{

            barThickness: barWidht,

            ticks: {

                min: 0,

                labelOffset: 0

            }

        }],

      xAxes: [{

            ticks: {

                min: 0

            }

        }]

    }

}

});
