The 3D Chart will display details about the points through tooltip, when the mouse is moved over the specific point.

Default tooltip

By default, tooltip is not visible. The tooltip can be enabled by setting the enable property in tooltipSettings to true and by injecting Tooltip3D module using Chart3D.Inject(Tooltip3D).

var chartData = [
    { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
    { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
    { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
    { month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
    { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
    { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart3D = new ej.charts.Chart3D({
    tooltip: { enable: true },
        primaryXAxis: {
            valueType: 'Category',
            labelRotation: -45,
            labelPlacement: 'BetweenTicks'
        },
       series:[{
            dataSource: chartData,
            xName: 'month',
            yName: 'sales',
            type: 'Column'
        }],
        wallColor: 'transparent',
        enableRotation: true,
        rotation: 7,
        tilt: 10,
        depth: 100,

}, '#element');

By default, tooltip track the mouse movement, but the tooltip can be set in fixed position by using the location property.

var chartData = [
    { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
    { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
    { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },

    { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
    { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart3D = new ej.charts.Chart3D({
    tooltip: { 
        enable: true,
        location: {  x: 120, y: 20 }
    },
        primaryXAxis: {
            valueType: 'Category',
            labelRotation: -45,
            labelPlacement: 'BetweenTicks'
        },
       series:[{
            dataSource: chartData,
            xName: 'month',
            yName: 'sales',
            type: 'Column'
        }],
        wallColor: 'transparent',
        enableRotation: true,

var chartData = [
    { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
    { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
    { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
    { month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
    { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
    { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart3D = new ej.charts.Chart3D({
    tooltip: { 
        enable: true,
        header: 'Unemployment',
        format: '<b>${series.name} : ${point.y}</b>'
    },
    primaryXAxis: {
        valueType: 'Category',
        labelRotation: -45,
        labelPlacement: 'BetweenTicks'
    },
   series:[{
        dataSource: chartData,
        xName: 'month',
        yName: 'sales',
        type: 'Column',
        name: "Month"
    }],
    wallColor: 'transparent',

    { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },

        enable: true,
        template: '#Unemployment'
    },
        primaryXAxis: {
