Vertical Chart in TypeScript Charts

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.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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');

    { x: 'Sep', y: 16 }, { x: 'Oct', y: 10 },
    { x: 'Nov', y: 4 }, { x: 'Dec', y: 0 }
];

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 control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

index.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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');

Fill

Use the fill property to set the fill color for empty points.

index.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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',
            fill: 'red'
        }
    }],
    isTransposed: true,
    title: 'Climate Graph-2012'
}, '#element');

];

Border

Use the border property to customize the border width and color for empty points.

index.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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',
            fill: 'red',
            border: { width: 2, color: 'green' }
        }
    }],
    isTransposed: true,
    title: 'Climate Graph-2012'
}, '#element');

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

index.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category, ISeriesRenderEventArgs } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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',
    seriesRender: (args: ISeriesRenderEventArgs) => {
        args.fill = '#ff6347';
    }
}, '#element');

    { 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: 'Nov', y: 4 }, { x: 'Dec', y: 0 }
];

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

index.ts
index.html
datasource.ts
import { Chart, SplineSeries, Category, IPointRenderEventArgs } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(SplineSeries, Category);

let chart: Chart = new 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',
    pointRender: (args: IPointRenderEventArgs) => {
        if (args.point.index % 2 !== 0) {
            args.fill = '#ff6347';
        }
        else {
            args.fill = '#009cb8';
        }
    }
}, '#element');
