DateTime axis

DateTime axis uses date time scale and displays the date time values as axis labels in the specified format.

index.js
index.html
var chartData = [
    { x: new Date(2000, 6, 11), y: 10 },
    { x: new Date(2002, 3, 7), y: 30 },
    { x: new Date(2004, 3, 6), y: 15 },
    { x: new Date(2006, 3, 30), y: 65 },
    { x: new Date(2008, 3, 8), y: 90 },
    { x: new Date(2010, 3, 8), y: 85 }
];
var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        // Date time scale in primary X Axis
        valueType: 'DateTime',
    },
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        type: 'Column'
    }],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,
    tilt: 10,
    depth: 100
}, '#element');

var ele = document.getElementById('container');

  ele.style.visibility = "visible";
}

Note: To use datetime axis, we need to inject DateTime3D module using Chart3D.Inject(DateTime3D) method and set the valueType of axis to DateTime.

DateTime category axis

DateTime category axis is used to display the date time values with non-linear intervals. For example, the business days alone have been depicted in a week here.

index.js
index.html
var chartData = [
    { x: new Date(2017, 11, 20), y: 21 }, { x: new Date(2017, 11, 21), y: 24 },
    { x: new Date(2017, 11, 22), y: 24 }, { x: new Date(2017, 11, 26), y: 70 },
    { x: new Date(2017, 11, 27), y: 75 }, { x: new Date(2018, 0, 2), y: 82 },
    { x: new Date(2018, 0, 3), y: 53 }, { x: new Date(2018, 0, 4), y: 54 },
    { x: new Date(2018, 0, 5), y: 53 }, { x: new Date(2018, 0, 8), y: 45 }
];
var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        valueType: 'DateTimeCategory',
        skeleton: 'Ed',
    },
    series: [
        {
            type: 'Column', xName: 'x', yName: 'y',
            dataSource: chartData
        }
    ],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,
    tilt: 10,
    depth: 100
}, '#element');

Note: To use datetime category axis, we need to inject DateTimeCategory3D module using the Chart3D.Inject(DateTimeCategory3D) method and set the valueType of axis to DateTimeCategory.

Range

Range of an axis will be calculated automatically based on the provided data. You can also customize the range of an axis using minimum, maximum and interval properties.

index.js
index.html
var chartData = [
    { x: new Date(2000, 6, 11), y: 10 }, { x: new Date(2002, 3, 7), y: 30 },
    { x: new Date(2004, 3, 6), y: 15 }, { x: new Date(2006, 3, 30), y: 65 },
    { x: new Date(2008, 3, 8), y: 90 }, { x: new Date(2010, 3, 8), y: 85 }
];

var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        valueType: 'DateTime',
        minimum: new Date(2000, 6, 1),
        maximum: new Date(2010, 6, 1), interval: 1
    },
    series: [
        {
            type: 'Column', xName: 'x', yName: 'y',
            dataSource: chartData
        }
    ],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,
    tilt: 10,
    depth: 100
}, '#element');

  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>
</body></html>

Interval customization

Date time intervals can be customized by using the interval and intervalType properties of the axis. For example, when you set interval as 2 and intervalType as Years, it considers 2 years as interval. DateTime axis supports following interval types,

Auto
Years
Months
Days
Hours
Minutes
Seconds

index.js
index.html
var chartData = [
    { x: new Date(2000, 6, 11), y: 10 }, { x: new Date(2002, 3, 7), y: 30 },
    { x: new Date(2004, 3, 6), y: 15 }, { x: new Date(2006, 3, 30), y: 65 },
    { x: new Date(2008, 3, 8), y: 90 }, { x: new Date(2010, 3, 8), y: 85 }
];
var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        valueType: 'DateTime',
        intervalType: 'Years'
    },
    series: [
        {

            dataSource: chartData
        }
    ],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,
    tilt: 10,
    depth: 100
}, '#element');

Applying padding to the range

Padding can be applied to the minimum and maximum extremes of the range by using the rangePadding property. DateTime axis supports the following types of padding,

None
Round
Additional

DateTime - None

When the rangePadding is set to None, minimum and maximum of an axis is based on the data.

index.js
index.html
var chartData = [
    { x: new Date(2017, 11, 20), y: 21 }, { x: new Date(2017, 11, 21), y: 24 },
    { x: new Date(2017, 11, 22), y: 24 }, { x: new Date(2017, 11, 26), y: 70 },
    { x: new Date(2017, 11, 27), y: 75 }, { x: new Date(2018, 0, 2), y: 82 },
    { x: new Date(2018, 0, 3), y: 53 }, { x: new Date(2018, 0, 4), y: 54 },
    { x: new Date(2018, 0, 5), y: 53 }, { x: new Date(2018, 0, 8), y: 45 }
];
var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        valueType: 'DateTime',
        rangePadding: 'None'
    },
    series: [
        {
            type: 'Column', xName: 'x', yName: 'y',
            dataSource: chartData
        }
    ],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,
    tilt: 10,
    depth: 100
}, '#element');

DateTime - Round

When the rangePadding is set to Round, minimum and maximum will be rounded to the nearest possible value, which is divisible by interval. For example, when the minimum is 15th Jan, interval is 1 and interval type is Month, then the axis minimum will be Jan 1st.

index.js
index.html
var chartData = [
    { x: new Date(2017, 11, 20), y: 21 }, { x: new Date(2017, 11, 21), y: 24 },

    { x: new Date(2017, 11, 27), y: 75 }, { x: new Date(2018, 0, 2), y: 82 },
    { x: new Date(2018, 0, 3), y: 53 }, { x: new Date(2018, 0, 4), y: 54 },
    { x: new Date(2018, 0, 5), y: 53 }, { x: new Date(2018, 0, 8), y: 45 }
];

    primaryXAxis: {
        valueType: 'DateTime',
        rangePadding: 'Round'
    },
    series: [
        {
            type: 'Column', xName: 'x', yName: 'y',
            dataSource: chartData
        }

    rotation: 7,
    tilt: 10,

DateTime - Additional

When the rangePadding is set to Additional, interval of an axis will be padded to the minimum and maximum of the axis.

Label format

The date can be formatted and parsed to all globalize format using the labelFormat property in an axis.

index.js
index.html
var chartData = [
    { x: new Date(2017, 11, 20), y: 21 }, { x: new Date(2017, 11, 21), y: 24 },
    { x: new Date(2017, 11, 22), y: 24 }, { x: new Date(2017, 11, 26), y: 70 },
    { x: new Date(2017, 11, 27), y: 75 }, { x: new Date(2018, 0, 2), y: 82 },
    { x: new Date(2018, 0, 3), y: 53 }, { x: new Date(2018, 0, 4), y: 54 },
    { x: new Date(2018, 0, 5), y: 53 }, { x: new Date(2018, 0, 8), y: 45 }
];
var chart3D = new ej.charts.Chart3D({
    primaryXAxis: {
        valueType: 'DateTime',
        labelFormat: 'yMd'
    },
    series: [
        {
            type: 'Column', xName: 'x', yName: 'y',
            dataSource: chartData
        }
    ],
    wallColor: 'transparent',
    enableRotation: true,
    rotation: 7,

The following table describes the result of applying some common date time formats to the labelFormat property.

Label Value	Label Format Property Value	Result	Description
new Date(2000, 03, 10)	EEEE	Monday	The Date is displayed in day format.
new Date(2000, 03, 10)	yMd	04/10/2000	The Date is displayed in month/date/year format.
new Date(2000, 03, 10)	MMM	Apr	The Shorthand month for the date is displayed.
new Date(2000, 03, 10)	hm	12:00 AM	Time of the date value is displayed as label.
new Date(2000, 03, 10)	hms	12:00:00 AM	The Label is displayed in hours:minutes:seconds format.

Custom label format

Axis also supports custom label format using placeholder like {value}°C, in which the value represent the axis label e.g 20°C.
