Define width on Y axis values column

[jfredsilva]

Can a maximum width be defined for the column where the Y axis values are defined?

Controlling Category Label Width:

While there isn't a direct maxWidth property for category labels, you can control their width and wrapping behavior using the following techniques:

• style.width within xAxis.labels: You can set a fixed width for the labels, which will force longer labels to wrap.

xAxis: {
    categories: ['Category 1', 'A very long category name', 'Category 3'],
    labels: {
        style: {
            width: '100px' // Set your desired width
        }
    }
}

• rotation within xAxis.labels: Rotate the labels to prevent overlap if they are too long.

xAxis: {
    labels: {
        rotation: -45 // Rotate labels for better readability
    }
}

• formatter within xAxis.labels: Use a formatter function to truncate or modify the labels dynamically.

xAxis: {
    labels: {
        formatter: function() {
            if (this.value.length > 10) {
                return this.value.substring(0, 10) + '...';
            } else {
                return this.value;
            }
        }
    }
}

Configure chart options:

Highcharts.chart('container', {
    chart: {
        type: 'bar'
    },
    title: {
        text: 'Fruit Consumption'
    },
    xAxis: {
        categories: ['A very long category name', 'Category 2',   'A very long long long long long category name', 'Category 3', 'A very long long long long long long long long category name',],
        labels: {
            style: {
                width: 100 // Set your desired width
            }
        }
    },
    yAxis: {
        title: {
            text: 'Fruit Eaten'
        },
        labels: {
            
        }
    },
    series: [{
        name: 'John',
        data: [5, 3, 4, 7, 2]
    }, {
        name: 'Jane',
        data: [2, 2, 3, 2, 1]
    }]
});
