AmChart V4 : make each label in category axes clickable and give for each label different functionality


I used amchart 4 to create a XYChart. I want to give each label on Y axes a different functionality: by clicking each of them, it will show a different modal.

data = [{ "name": "name1",
          "value1": "1",
          "value2": "2"},
 
        { "name": "name2",
          "value1": "10"
          "value2": "20"}]

    var chart = am4core.create("chartdiv", am4charts.XYChart);
    chart.data = data;

    var categoryAxis = chart.yAxes.push(new am4charts.CategoryAxis());
    categoryAxis.dataFields.category = "name";

    var dateAxis = chart.xAxes.push(new am4charts.DateAxis());

To make each label on Y axes clickable and show a modal, I add this:

categoryAxis.renderer.labels.template.events.on("hit", function(event){
     $(document).ready(function(){
            $("#mymodal").modal('show');
        });
})

But of course, all it does overwriting and give the same modal for all labels. Is there a way to access the labels individually (create a forloop over the labels)?

    I gave each label a different modal to show (Thanks to my teamleader Yaniv for help =P )

    I added to data a variable "copy_num":

    data = [{ "name": "name1",
              "value1": "1",
              "value2": "2",
              "copy_num": "1"},
     
            { "name": "name2",
              "value1": "10"
              "value2": "20",
              "copy_num": "2"}]
    

    Then:

    categoryAxis.renderer.labels.template.events.on("hit", function(event){
         $(document).ready(function(){
              $("#chartcopy" + 
                  event.target.dataItem.dataContext.copy_num).modal('show');
            });
    })
    

    In HTML I added the modals:

    <div class="copy modal fade" id="chartcopy1" role="dialog"></div>
    <div class="copy modal fade" id="chartcopy2" role="dialog"></div>
    

    2 solution:

    I used 'range' to make new labels:

    https://www.amcharts.com/docs/v4/tutorials/grouping-axis-labels-using-ranges/ https://www.amcharts.com/docs/v4/tutorials/using-axis-ranges-on-radar-chart/

    var range = categoryAxis.axisRanges.create();
    range.category = "name1";
    range.endCategory = "name2";
    range.label.text = "label_1";
    range.label.verticalCenter = "middle";
    range.label.events.on("hit", function(event){{
        $(document).ready(function(){{
            $({modal_to_show}).modal('show');
        }});
    }})
    

    Add some nice design:

    range.label.cursorOverStyle = am4core.MouseCursorStyle.pointer;
    
    range.label.background = new am4core.RoundedRectangle();
    range.label.background.cornerRadius(5, 5, 5, 5);
    range.label.background.fill = am4core.color("#eee");
    
    range.label.truncate = true;
    range.label.maxWidth = 180;
    
    var hoverLabelState = range.label.background.states.create("hover");
    hoverLabelState.properties.fill = am4core.color("#C0C0C0");
    

    To desable the old labels:

    categoryAxis.renderer.labels.template.adapter.add("textOutput", function(text
                                                                      {return "";});
