18 Apr 202322 minutes to read

You can customize axis value types and min and max values of the sparkline.

Change value type of the sparkline

You can change the sparkline value type by setting the [valueType] property to [Numeric], [Category], or [DateTime].

DateTime

You can assign date-time values to the sparkline by setting the [valueType] property to [DateTime].

import { Sparkline } from '@syncfusion/ej2-charts';

let sparkline: Sparkline = new Sparkline({
    height: '150px',
    width: '130px',
    dataSource: [
            { xDate: new Date(2018, 0, 1), x: 0, yval: 4 },
            { xDate: new Date(2018, 0, 2), x: 1, yval: 4.5 },
            { xDate: new Date(2018, 0, 3), x: 2, yval: 8 },
            { xDate: new Date(2018, 0, 4), x: 3, yval: 7 },
            { xDate: new Date(2018, 0, 5), x: 4, yval: 6 },
            { xDate: new Date(2018, 0, 8), x: 5, yval: 8 },
            { xDate: new Date(2018, 0, 9), x: 6, yval: 8 },
            { xDate: new Date(2018, 0, 10), x: 7, yval: 6.5 },
            { xDate: new Date(2018, 0, 11), x: 8, yval: 4 },
            { xDate: new Date(2018, 0, 12), x: 9, yval: 5.5 }
        ],
    // Assign the dataSource values to series of sparkline 'xName and yName'
    xName: 'xDate', yName: 'yval',
    // Assign the "Column" as type of the sparkline
    type:'Column',
    // Assign the "DateTime" as value type to the sparkline
    valueType: 'DateTime'
});
sparkline.appendTo("#element");

Category

You can assign category values to the sparkline by setting [valueType] to [Category].

import { Sparkline } from '@syncfusion/ej2-charts';

let sparkline: Sparkline = new Sparkline({

Change min and max values of axis

You can change the min and max values of x-axis by setting the [minX] and [maxX] values to the [axisSettings] property. You can also change the min and max values of y-axis by setting the [minY] and [maxY] values to the [axisSettings] property.

import { Sparkline } from '@syncfusion/ej2-charts';

let sparkline: Sparkline = new Sparkline({
    height: '150px',
    width: '130px',
    dataSource: [
            { x: 0, yval: 50 },
            { x: 1, yval: 30 },
            { x: 2, yval: 20 },
            { x: 3, yval: 30 },
            { x: 4, yval: 50 },
            { x: 5, yval: 40 },
            { x: 6, yval: 20 },
            { x: 7, yval: 10 },
            { x: 8, yval: 30 },
            { x: 9, yval: 10 },
            { x: 10, yval: 40 }
        ],
    // Assign the dataSource values to series of sparkline 'xName and yName'
    xName: 'x', yName: 'yval',
    // Set min and max values to the y-axis of sparkline
    axisSettings: {
            minY: 0, maxY: 150
    },
    // Assign the 'Column' as type of the sparkline
    type:'Column',
    // Assign the 'Numeric' as value type of the sparkline
    valueType: 'Numeric'
});
sparkline.appendTo("#element");

Change value of axis

You can set horizontal axis line value of the sparkline by setting [value] to the [axisSettings] property. The following code example shows this.

import { Sparkline } from '@syncfusion/ej2-charts';

 let sparkline: Sparkline = new Sparkline({
    height: '150px',
    width: '130px',
    dataSource: [
            { x: 0, yval: 50 },
            { x: 1, yval: 30 },
            { x: 2, yval: 20 },
            { x: 3, yval: 30 },
            { x: 4, yval: 50 },
            { x: 5, yval: 40 },
            { x: 6, yval: 20 },
            { x: 7, yval: 10 },
            { x: 8, yval: 30 },
            { x: 9, yval: 10 },
            { x: 10, yval: 40 }
        ],
    // Assign the dataSource values to series of sparkline 'xName and yName'
    xName: 'x', yName: 'yval',
    // Set the value to horizontal axis of sparkline
    axisSettings: {
          value: 25
    },
    // Assign the 'Column' as type of the sparkline
    type:'Column',
    // Assign the 'Numeric' as value type of the sparkline
    valueType: 'Numeric'
});
sparkline.appendTo("#element");

Axis line customization

Axis of the sparkline can be collapsed using the [visible] property in [lineSettings]; this is not applicable for win-loss. You can customize the [color], [width], [opacity], and [dashArray] of axis line.

import { Sparkline } from '@syncfusion/ej2-charts';

let sparkline: Sparkline = new Sparkline({
    height: '150px',
    width: '130px',
    dataSource: [
            { x: 0, yval: 50 },
            { x: 1, yval: 30 },
            { x: 2, yval: 20 },
            { x: 3, yval: 30 },
            { x: 4, yval: 50 },
            { x: 5, yval: 40 },
            { x: 6, yval: 20 },
            { x: 7, yval: 10 },
            { x: 8, yval: 30 },
            { x: 9, yval: 10 },
            { x: 10, yval: 40 }
        ],
    // Assign the dataSource values to series of sparkline 'xName and yName'
    xName: 'x', yName: 'yval',
    // Set the value to horizontal axis
    axisSettings: {
    // To configure axis line settings
         lineSettings: {
            visible: true,
            color: "#ff14ae",
            dashArray: '5,3'
            }
    },
    // Assign the value type as 'Numeric' to the sparkline
    valueType: 'Numeric'
});
sparkline.appendTo("#element");
