Axis Crossing

An axis can be positioned in the chart area using crossesAt and crossesInAxis properties. The crossesAt property specifies the values (datetime, numeric, or logarithmic) at which the axis line has to be intersected with the vertical axis or vice-versa, and the crossesInAxis property specifies the axis name with which the axis line has to be crossed.

var chartData = [
      { country: "USA", gold: 50, silver: 70, bronze: 45 },
      { country: "China", gold: 40, silver: 60, bronze: 55 },
      { country: "Japan", gold: 70, silver: 60, bronze: 50 },
      { country: "Australia", gold: 60, silver: 56, bronze: 40 },
      { country: "France", gold: 50, silver: 45, bronze: 35 },
      { country: "Germany", gold: 40, silver: 30, bronze: 22 },
      { country: "Italy", gold: 40, silver: 35, bronze: 37 },
      { country: "Sweden", gold: 30, silver: 25, bronze: 27 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        // label placement as on ticks
        labelPlacement: 'OnTicks',
        title: 'Countries'
    },
    primaryYAxis: {
        minimum: 0, maximum: 80,
        interval: 20, title: 'Medals'
    },
    series:[{
        dataSource: chartData,
        xName: 'country', yName: 'gold',
        name: 'Gold', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'silver',
        name: 'Silver', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'bronze',
        name: 'Bronze', type: 'Column'
    }],
    title: 'Olympic Medals'
}, '#element');

Title

You can add a title to the axis using title property to provide quick information to the user about the data plotted in the axis. Title style can be customized using titleStyle property of the axis.

var chartData = [
      { country: "USA", gold: 50, silver: 70, bronze: 45 },
      { country: "China", gold: 40, silver: 60, bronze: 55 },
      { country: "Japan", gold: 70, silver: 60, bronze: 50 },
      { country: "Australia", gold: 60, silver: 56, bronze: 40 },
      { country: "France", gold: 50, silver: 45, bronze: 35 },
      { country: "Germany", gold: 40, silver: 30, bronze: 22 },
      { country: "Italy", gold: 40, silver: 35, bronze: 37 },
      { country: "Sweden", gold: 30, silver: 25, bronze: 27 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Countries'
    },
    primaryYAxis: {
        minimum: 0, maximum: 80,
        interval: 20, title: 'Medals',
        labelFormat: '${value}K',
        //Axis title text style
        titleStyle: {
            size: '16px', color: 'grey',
            fontFamily : 'Segoe UI', fontWeight : 'bold'
        }
    },
    series:[{
        dataSource: chartData,
        xName: 'country', yName: 'gold',
        name: 'Gold', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'silver',
        name: 'Silver', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'bronze',
        name: 'Bronze', type: 'Column'
    }],
    title: 'Olympic Medals'
}, '#element');

Title Rotation

By using the titleRotation property, you can rotate the axis title from 0 to 360 degree.

var chartData = [
      { country: "USA", gold: 50, silver: 70, bronze: 45 },
      { country: "China", gold: 40, silver: 60, bronze: 55 },
      { country: "Japan", gold: 70, silver: 60, bronze: 50 },
      { country: "Australia", gold: 60, silver: 56, bronze: 40 },
      { country: "France", gold: 50, silver: 45, bronze: 35 },
      { country: "Germany", gold: 40, silver: 30, bronze: 22 },
      { country: "Italy", gold: 40, silver: 35, bronze: 37 },
      { country: "Sweden", gold: 30, silver: 25, bronze: 27 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Countries', titleRotation: 90
    },
    primaryYAxis: {
        minimum: 0, maximum: 80,
        interval: 20, title: 'Medals',
        labelFormat: '${value}K',
        //Axis title text style
        titleStyle: {
            size: '16px', color: 'grey',
            fontFamily : 'Segoe UI', fontWeight : 'bold'
        }
    },
    series:[{
        dataSource: chartData,
        xName: 'country', yName: 'gold',
        name: 'Gold', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'silver',
        name: 'Silver', type: 'Column'
    }, {
        dataSource: chartData,
        xName: 'country', yName: 'bronze',
        name: 'Bronze', type: 'Column'

Tick Lines Customization

You can customize the  width, color and size of the minor and major tick lines, using majorTickLines and
minorTickLines properties in the axis.

var chartData= [
    { x: 'Jan', y: 60 }, { x: 'Feb', y: 50 }, { x: 'Mar', y: 64 },
    { x: 'Apr', y: 63 }, { x: 'May', y: 81 }, { x: 'Jun', y: 64 },
    { x: 'Jul', y: 82 }, { x: 'Aug', y: 96 }, { x: 'Sep', y: 78 },
    { x: 'Oct', y: 60 }, { x: 'Nov', y: 58 }, { x: 'Dec', y: 56 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        //Tick lines customization
        majorTickLines : {
            color : 'blue',
            width : 5
        },
        minorTickLines : {
            color : 'red',
            width : 0
        }
    },
    primaryYAxis: {
        title: 'Temperature (Fahrenheit)',
        //Grid lines customization
        majorTickLines : {
            color : 'blue',
            width : 5
        },
        minorTickLines : {
            color : 'red',
            width : 0
        }
    },
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        name: 'Sales', type: 'Column'
    }],
    title: 'Temperature flow over months'
}, '#element');

Grid Lines Customization

You can customize the width, color and dashArray of the minor and major grid lines, using majorGridLines
and minorGridLines properties in the axis.

var chartData= [
    { x: 'Jan', y: 60 }, { x: 'Feb', y: 50 }, { x: 'Mar', y: 64 },
    { x: 'Apr', y: 63 }, { x: 'May', y: 81 }, { x: 'Jun', y: 64 },

    { x: 'Oct', y: 60 }, { x: 'Nov', y: 58 }, { x: 'Dec', y: 56 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        //Grid lines customization
        majorGridLines : {
            color : 'blue',
            width : 1
        },
        minorGridLines : {
            color : 'red',
            width : 0
        }

Multiple Axis

In addition to primary X and Y axis, we can add n number of axis to the chart. Series can be associated with this axis, by mapping with axis’s unique name.

var chartData = [
    { x: 'Jan', y: 15, y1: 33 }, { x: 'Feb', y: 20, y1: 31 }, { x: 'Mar', y: 35, y1: 30 },
    { x: 'Apr', y: 40, y1: 28 }, { x: 'May', y: 80, y1: 29 }, { x: 'Jun', y: 70, y1: 30 },
    { x: 'Jul', y: 65, y1: 33 }, { x: 'Aug', y: 55, y1: 32 }, { x: 'Sep', y: 50, y1: 34 },
    { x: 'Oct', y: 30, y1: 32 }, { x: 'Nov', y: 35, y1: 32 }, { x: 'Dec', y: 35, y1: 31 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Months',
        valueType: 'Category',
        interval: 1
    },
    primaryYAxis: {
        minimum: 0, maximum: 90, interval: 10,
        lineStyle: { width: 0 },
        title: 'Temperature (Fahrenheit)',
        labelFormat: '{value}°F'
    },
     // Initializing multiple axis
    axes:[
        {
            majorGridLines: { width: 0 },
            rowIndex: 0, opposedPosition: true,
            lineStyle: { width: 0 },
            minimum: 24, maximum: 36, interval: 2,
            name: 'yAxis', title: 'Temperature (Celsius)',
            labelFormat: '{value}°C'
        }
    ],
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        name: 'Germany', type: 'Column'
    },{
        dataSource: chartData, width:2,
        xName: 'x', yName: 'y1', yAxisName: 'yAxis',
        name: 'Japan', type: 'Line',
        marker: { visible: true, width: 10, height: 10, border: { width: 2, color: '#F8AB1D' } }
    }],
    title: 'Weather Condition'
}, '#element');

Inversed Axis

When an axis is inversed, highest value of the axis comes closer to origin and vice versa. To place an axis in inversed manner set this property
isInversed to true.

var chart = new ej.charts.Chart({
        //Initializing Primary X Axis
        primaryXAxis: {
            valueType: 'Category',
            title: 'Years',
            opposedPosition: true,
            isInversed: true
        },

        //Initializing Primary Y Axis
        primaryYAxis:
        {
            title: 'Exchange rate (INR per USD)',
            edgeLabelPlacement: 'Shift',
            labelIntersectAction: 'Rotate45',
            isInversed: true
        },
        series: [
            {
                type: 'Column',
                dataSource: [
                    { x: 2008, y: 15.1 }, { x: 2009, y: 16 }, { x: 2010, y: 21.4 },
                    { x: 2011, y: 18 }, { x: 2012, y: 16.2 }, { x: 2013, y: 11 },
                    { x: 2014, y: 7.6 }, { x: 2015, y: 1.5 }
                ],
                marker: { dataLabel: { visible: true }},
                xName: 'x',
                yName: 'y', name: 'Years',
            },

Opposed Position

To place an axis opposite from its original position, set opposedPosition property of the axis to true.

var chart = new ej.charts.Chart({
        //Initializing Primary X Axis
        primaryXAxis: {
            valueType: 'Category',
            title: 'Years',

            isInversed: true
        },

        //Initializing Primary Y Axis
        primaryYAxis:
        {
            title: 'Exchange rate (INR per USD)',
            edgeLabelPlacement: 'Shift',
            labelIntersectAction: 'Rotate45',
            isInversed: true
        },
        series: [
            {
                type: 'Column',
                dataSource: [
