Is there a way to switch the cursor to a pointer when hovering over a bar on a ChartJS bar graph?

Here's the chart I created:

createChart = function (name, contributions, idArray) {
    globalIdArray = idArray;
    var ctx = document.getElementById("myChart");
    var myChart = new Chart(ctx, {
        type: "bar",
        data: {
            labels: name,
            datasets: [{
                label: "Contributions",
                data: contributions,
                backgroundColor: [
                    'rgba(0, 255, 0, 0.2)',
                    'rgba(0, 255, 0, 0.2)',
                    'rgba(0, 255, 0, 0.2)',
                    'rgba(0, 255, 0, 0.2)',
                    'rgba(0, 255, 0, 0.2)'
                ]
            }]
        },
        options: {
            scales: {
                yAxes: [{
                    ticks: {
                        beginAtZero: true
                    }
                }]
            },
            onClick: handleClick,
            onHover: handleHover
        }
    });

This HTML is actually all JavaScript code that exists inside a canvas element.

<canvas chart-hover="onHover" id="myChart" width="200" height="200"></canvas>

When I click on a bar in the chart, it acts as a "drill in" and takes me to a page with more details. Here's the code for that functionality:

function handleClick(e) {
    debugger;
    var activeElement = myChart.getElementAtEvent(e);
    var designerId = _idArray[activeElement[0]._index];
    window.location.href = "/Display/search/index?designerId=" + designerId;
}

I want the cursor to change to a pointer when hovering over the bar, indicating that it can be clicked. I found some examples on Stack Overflow, but they were outdated. I also tried another solution from a post which didn't work for me.

How to change cursor style to pointer on hovering over points of the chart?

Does anyone know how I can achieve this using the latest version of ChartJS?

Answer №1

When working with a line chart, I wanted the cursor to change only when hovering over a bar or point. To achieve this, I devised a simple solution that involves placing your function outside of the chart declaration.

var chart = new Chart(ctx, {
    data: {...},
    options: {
     onHover: graphHover
    }
});
function graphHover(e, array) {
    if(array.length > 0) {
        e.target.style.cursor = 'pointer';
    }else {
        e.target.style.cursor = '';
    }
}

Answer №2

One can utilize the cursor property in CSS to customize the appearance of the cursor on a web page. For instance:

span.pointer {
    cursor: pointer;
}

span.move {
    cursor: move;
}

span.text {
    cursor: text;
}
