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 or Vue.js sections below depending on what framework you're using. Also see API documentation common to both frameworks.

React

Installation

Install uplot-react package with uplot dependency:

• Using npm: $ npm install uplot-react uplot
• Using yarn: $ yarn add uplot-react uplot

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

Vue.js

Installation

Install uplot-vue package with uplot dependency:

• Using npm: $ npm install uplot-vue uplot
• Using yarn: $ yarn add uplot-vue uplot

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
