uPlot wrappers

A collection of uPlot wrappers that allow you to work with charts declaratively inside your favorite framework.

Table of Contents

Motivation

While several other uPlot wrappers already exist, all of them have one of the following limitations:

  1. They create uPlot instance once, during component mount phase, and expect you to handle all the update logic yourself.
  2. They recreate uPlot instance anew whenever the props change, even if the instance can be updated to reflect the changes.

In comparison this library tries it's best not to recreate the uPlot instance once the props change. Instead of recreation it tries to use uPlot public API to keep it up to date with the props.

Getting started

See React, Vue.js or Svelte sections below depending on what framework you're using. Also see API documentation common to all frameworks.

React

Installation

Install uplot-react package with uplot dependency:

You also need React 16.8 or above to be installed inside your project tree.

How to use

import React from 'react';
import uPlot from 'uplot';
import UplotReact from 'uplot-react';
import 'uplot/dist/uPlot.min.css';

const Chart = () => (
    <UplotReact options={options} data={data} target={target} onCreate={(chart) => {}} onDelete={(chart) => {}} />
);

Demo

See the live demo

You can also run the demo app locally:

$ git clone https://github.com/skalinichev/uplot-wrappers.git

$ cd uplot-wrappers && yarn install && yarn run serveReact

ReactJS Demo

Vue.js

Installation

Install uplot-vue package with uplot dependency:

You also need Vue.js to be installed inside your project tree (both 2.6 and 3.x versions are supported).

How to use

Using template

<template>
    <UplotVue :data="data" :options="options" :target="target" @create="onCreate" @delete="onDelete" />
</template>
<script>
    // Vue.js 2
    import Vue from 'vue';
    // Vue.js 3
    import { createApp } from 'vue';
    import uPlot from 'uplot';
    import UplotVue from 'uplot-vue';
    import 'uplot/dist/uPlot.min.css';

    // Vue.js 2
    const Chart = Vue.extend({ components: { uplotvue: UplotVue } });
    // Vue.js 3
    const Chart = createApp({ components: { uplotvue: UplotVue } });
</script>

Using JSX

// Vue.js 2
import Vue from 'vue';
// Vue.js 3
import { createApp } from 'vue';
import uPlot from 'uplot';
import UplotVue from 'uplot-vue';
import 'uplot/dist/uPlot.min.css';

{
    ...,
    render() {
        return (
            <UplotVue
                options={options}
                data={data}
                target={target}
                onDelete={(chart) => {}}
                onCreate={(chart) => {}}
            />
        );
    }
}

Note: Property changes by mutation are not supported due to Vue limitation You have to create a copy of the property, i.e. replace it instead, see an example for the general idea.

Demo

See the Vue.js 2 live demo

You can also run the demo app locally:

$ git clone https://github.com/skalinichev/uplot-wrappers.git

$ cd uplot-wrappers && yarn install

Vue.js 2:

$ yarn run serveVue

Vue.js 3:

$ yarn run serveVue3

Svelte

Installation

Install uplot-svelte package with uplot dependency:

You also need Svelte to be installed inside your project tree. UplotSvelte component is compatible with Svelte and SvelteKit projects.

How to use

<script lang="ts">
    import UplotSvelte from 'uplot-svelte';
    import uPlot from 'uplot';
    import 'uplot/dist/uPlot.min.css';

    ...
</script>

<UplotSvelte {options} {data} onCreate={onCreate} onDelete={onDelete} />

Demo

See the example Svelte example

You can also run the demo app locally:

$ git clone https://github.com/skalinichev/uplot-wrappers.git

$ cd uplot-wrappers && yarn install && yarn run serveSvelte

ParameterRequirementDescription
optionsrequiredOptions for uPlot. Passed as the first argument to uPlot constructor: new uPlot(options)
datarequiredData for uPlot. Passed as the second argument to uPlot constructor: new uPlot(options, data)
targetoptionalTarget html element for uPlot. Passed as the third argument to uPlot constructor: new uPlot(options, data, target) A new div target element will be created automatically if none is passed in the props
onCreateoptionalCallback function, invoked upon uPlot instance creation or recreation
onDeleteoptionalCallback function, invoked before uPlot instance gets destroyed, either because the props has changed so much it's impossible to update the chart or because the component is about to be unmounted
className/classoptionalA class name passed over to the automatically created target div element. Class name is ignored when the 'target' prop is used.
resetScalesoptionalFlag controlling whether to reset the scales on data change. Defaults to true.
