Vertical Chart

To draw a chart in a vertical manner, change the orientation of the axis using the isTransposed property, which is supported by all series types.

index.js
index.html
var chartData = [
    { x: 'Jan', y: -1 }, { x: 'Feb', y: -1 },
    { x: 'Mar', y: 2 }, { x: 'Apr', y: 8 },
    { x: 'May', y: 13 }, { x: 'Jun', y: 18 },
    { x: 'Jul', y: 21 }, { x: 'Aug', y: 20 },
    { x: 'Sep', y: 16 }, { x: 'Oct', y: 10 },
    { x: 'Nov', y: 4 }, { x: 'Dec', y: 0 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Month',
        valueType: 'Category'
    },
    primaryYAxis: {
        minimum: -5, maximum: 25, interval: 10,
        labelFormat: '{value}˚C',
        majorGridLines: { width : 0 }
    },
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        type: 'Spline', width:2,
        marker: { visible: true }
    }],
    isTransposed: true,
    title: 'Climate Graph-2012'
}, '#element');

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

index.js
index.html
var chartData = [
    { x: 'Jan', y: -1 }, { x: 'Feb', y: -1 },
    { x: 'Mar', y: 2 }, { x: 'Apr', y: 8 },
    { x: 'May', y: 13 }, { x: 'Jun', y: 18 },
    { x: 'Jul', y: 21 }, { x: 'Aug', y: 20 },
    { x: 'Sep', y: 16 }, { x: 'Oct', y: 10 },
    { x: 'Nov', y: 4 }, { x: 'Dec', y: 0 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Month',
        valueType: 'Category'
    },
    primaryYAxis: {
        minimum: -5, maximum: 25, interval: 10,
        labelFormat: '{value}˚C',
        majorGridLines: { width : 0 }
    },
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        type: 'Spline', width:2,
        marker: { visible: true }
    }],
    isTransposed: true,
    title: 'Climate Graph-2012'
}, '#element');

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap.

index.js
index.html
var chartData = [
    { x: 'Jan', y: -1 }, { x: 'Feb', y: -1 },
    { x: 'Mar', y: 2 }, { x: 'Apr', y: null },
    { x: 'May', y: 13 }, { x: 'Jun', y: 18 },
    { x: 'Jul', y: 21 }, { x: 'Aug', y: 20 },
    { x: 'Sep', y: undefined }, { x: 'Oct', y: 10 },
    { x: 'Nov', y: 4 }, { x: 'Dec', y: 0 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Month',
        valueType: 'Category'
    },
    primaryYAxis: {
        minimum: -5, maximum: 25, interval: 10,
        labelFormat: '{value}˚C',
        majorGridLines: { width : 0 }
    },
    series:[{
        dataSource: chartData, 
        xName: 'x', yName: 'y',
        type: 'Spline', width:2,
        marker: { visible: true, width: 7, height: 7, isFilled: true },
        emptyPointSettings: {
            mode: 'Zero'
        }
    }],
    isTransposed: true,
    title: 'Climate Graph-2012'
}, '#element');

Events

Series render

The seriesRender event allows you to customize series properties, such as data, fill, and name, before they are rendered on the chart.
