Generate SVG sparklines with JavaScript without any external dependency.
This lib is available as a NPM package. To install it, use the following command:
install @fnando/sparkline --save
If you're using Yarn (and you should):
add @fnando/sparkline
You'll have to call sparkline.sparkline(svg, values, options) directly if you're loading the script without compiling your script (e.g. webpack). Otherwise you can simply import sparkline from "@fnando/sparkline";.
sparkline(svg, values, options = {})svg: This is a <svg> reference that must contain three required attributes (width, height, and stroke-width). These attributes are used to calculate the drawing area.values: You can either provide an array of numbers or an array of objects that respond to .value. If you have a different data structure, see options.fetch.options: This optional argument allows you to further customize the sparkline. The available options are:fetch: Use this function to return the value if you have a different data structure that's not natively supported by sparkline.onmousemove: By setting this callback function, you'll enable the interactive mode (unless you set options.interactive to false). The callback signature is callback(event, datapoint), where datapoint is an object containing the value, x/y coordinates, and the item index.onmouseout: This callback function is called every time the mouse leaves the SVG area. You can use it to hide things like tooltips.spotRadius: Set the spot radius. The default is 2.cursorWidth: Set the cursor width. The default is 2.interactive: When true, this enables the interactive mode. You don't have to set this option if you're providing a onmousemove callback.This is the minimum working example:
width, height and stroke-width attributes must be defined on the target SVG -->
class="sparkline" width="100" height="30" stroke-width="3"></svg>
ipt>
arkline(document.querySelector(".sparkline"), [1, 5, 2, 4, 8, 3, 7]);
ript>
You can change the colors by either setting the attributes directly to the SVG element or using CSS, like the following:
ust the line */
rkline {
roke: red;
ll: none;
ine with highlight area */
rkline {
roke: red;
ll: rgba(255, 0, 0, .3);
hange the spot color */
rkline--spot {
roke: blue;
ll: blue;
hange the cursor color */
rkline--cursor {
roke: orange;
