Table of Contents

Use

The sparkline-svg package exports a Sparkline class, which can be constructed with or without an array of values used to generate the sparkline.

import Sparkline from 'sparkline-svg';
 
const sparkline= new Sparkline();
// or
const sparkline = new Sparkline(values);

get d(): string

sparkline.d returns the <path />'s d attribute for the sparkline (stroke) itself.

get dataUri(): string

sparkline.dataUri returns the sparkline SVG as a data URI, i.e. data:image/svg+xml;base64,.... This is particularly useful for CSS background images.

get outerHTML(): string

sparkline.outerHTML returns a string of the HTML for an SVG containing the sparkline.

setDecimals(decimals: number): this

Sets the number of decimal places used to generate the sparkline. A larger number of decimal places will result in better precision, but a larger file size.

Default: 4

setDesc(desc: string): this

Sets the description of the sparkline. Used to populate the <desc> element.

Default: 'A line graph representation of a value's change over time.'

setDescription(desc: string): this

Synonymous with setDesc.

setFill(fill: string): this

Sets the color of the area underneath the sparkline.

Default: 'transparent'

setStroke(stroke: string): this

Sets the width of the sparkline itself. If using a number, this will be relative to the view box height and width.

setTitle(title: string): this

setValues(values: number[]): this

Sets the values used to generate the sparkline. These can also be provided in the constructor.

Default: []

setViewBoxHeight(viewBoxHeight: number): this
