concealed highcharts data labels

I attempted to create a bar chart using Highcharts, and initially it worked fine. However, I encountered an issue when displaying multiple indicators - the datalabels for certain data points are hidden. For example, the datalabel for "provinsi aceh" is not visible:

How can I adjust the settings so that all datalabels appear without overlapping each other? Note that the maximum number of indicators is 4.

Below is the code for my graph:

Highcharts.chart(chartId, {
                            chart: {
                              type: 'column'
                            },
                            title: {
                              text: chartname,
                              align: 'center'
                            },
                            plotOptions: {
                                series: {
                                pointPadding: 0.4,
                                groupPadding: 0.1
                              }
                            },  
                            tooltip: {
                                shared: true,
                            },
                            xAxis: {
                              type: 'category',
                            },
                            plotOptions: {
                              series: {
                                borderWidth: 0,
                                dataLabels: {
                                  enabled: true
                                }
                              }
                            },
                            series: grafikmaindata,
                            drilldown: seriessubgrafik[0],
                            exporting: {
                                buttons: {
                                    copyToClipboard: {
                                        text: 'Copy Chart',
                                        _titleKey: 'contextButtonTitle',
                                        align: 'right',
                                        onclick: function () {
                                            // Call the function to copy the chart to the clipboard
                                            copyHtmlToClipboard(this.container);
                                        },            
                                    }
                                }

Answer №1

If you wish to display all dataLabels, simply activate the allowOverlap feature:

  dataLabels: {
        enabled: true,
        allowOverlap: true
      }

To adjust overlaping dataLabels, you can modify their y position:

  chart: {
    type: 'column',
    events: {
      load() {
        let point = this.series[2].points[3];
        point.update({
          x: point.x,
          dataLabels: {
            y: 10
          }
        })
      }
    }
  },
