A step-by-step guide on implementing tooltips for x-axis labels in Highcharts

I am working with a chart that has a complex options configuration like this:

this.chartOptions = {
{
    "responsive": {
        "rules": [
            {
                "condition": {
                    "maxWidth": 500
                },
                "_id": "highcharts-7kdse7e-57"
            }
        ]
    },
    "chart": {
        "type": "line",
        "style": {
            "cursor": "pointer"
        },
        "zooming": {
            "type": "x"
        }
    },
    "title": {
        "text": "",
        "align": "left"
    },
    "subtitle": {
        "text": "",
        "align": "left"
    },
    "credits": {
        "enabled": false
    },
    "legend": {
        "enabled": false
    },
    "plotOptions": {
        "area": {
            "marker": {
                "radius": 2
            },
            "lineWidth": 1,
            "color": {
                "linearGradient": {
                    "x1": 0,
                    "y1": 0,
                    "x2": 0,
                    "y2": 1
                },
                "stops": [
                    [
                        0.5,
                        "#95AAB8"
                    ],
                    [
                        1,
                        "#F3F6F7"
                    ]
                ]
            },
            "states": {
                "hover": {
                    "lineWidth": 1
                }
            },
            "threshold": null
        }
    },
    "series": [
        {
            "data": [
                [
                    1709164800000,
                    0
                ],
              ...
            ],
            "lineColor": "#7E97A8",
            "name": "",
            "type": "area"
        }
    ],
    "exporting": {
        "buttons": {
            "contextButton": {
                "enabled": false
            }
        }
    },
    "xAxis": {
        "type": "datetime",
        "lineColor": "#C3C5C9",
        "labels": {}
    },
    "yAxis": {
        "title": {
            "text": ""
        },
        "labels": {
            "style": {
                "color": "#3F5C69"
            }
        }
    },
    "tooltip": {}
}
};

After searching online, I was unable to find a solution for my issue.
I need the tooltip to dynamically appear over the labels of the x-axis in the chart.
I also have another tooltip on the chart that needs to work simultaneously.
I have tried everything but haven't found a working solution.
What can I do to resolve this?

Answer №1

If you're working with Highcharts, you may have noticed that there are no default events for adding tooltips to axis labels. However, fear not! There is a handy custom-events plugin available that enables you to incorporate hover events for the axis labels. This makes it simple to display tooltips when users hover over those labels.

Check out this demo showcasing how to implement this feature: https://stackblitz.com/edit/highcharts-angular-line-ppt2px?file=src%2Fapp%2Fapp.component.ts

For more detailed information and documentation on the custom-events plugin, visit:
