Hello,
Try to add these in Configurations option tab :
in javascript snippet ,use this script for labels in format you change based on x axis or y axis
dataLabels: {
enabled: true, format: '{point.name}: {point.y}',
style: {
fontSize: '16px',
fontWeight: 'bold',
color: '#000'
}
}
for zoom in try in this style add two buttons
<button onclick="setZoom(0.75)">Zoom Out (75%)</button><button onclick="setZoom(1.5)">Zoom In (150%)</button>
var currentZoom = 1;
function setZoom(scale) { currentZoom = scale; document.getElementById('your container name').style.transform = `scale(${scale})`;}
