Readme
JSCharting is a JavaScript data visualization library offering seamless usage with React across all devices and platforms. Every JSCharting license includes a full suite of 150+ chart types including standards such as pie charts, line charts, donut and bar charts. In addition, advanced chart types including Gantt charts, JavaScript Org Charts, interactive charts for stock and finance, seamless grid and calendar charts, JavaScript maps, and micro charts all for no additional charge. JSCharting has all the features you need and many you don't yet know you want.
Example Charts: Chart Types | Feature Examples
Official JSCharting plugin for ReactJS
A react wrapper to use JSCharting charting library as a react chart component.
Table of Contents
Install
Install the jscharting-react plugin.
npm i -D jscharting-react
Run Examples
Clone the github repo locally. Example charts are located in the /examples
folder.
To view the examples you can run the webpack dev server: localhost:8080
npm run start-examples
Or build the project manually.
npm run build-examples
Usage
Simple example
This example shows how you can use the JSCharting
component of the jscharting-react
module to make a bar chart.
import React from 'react';
import { JSCharting } from 'jscharting-react';
const config = {
type: 'horizontal column',
series: [
{
points: [
{ x: 'A', y: 50 },
{ x: 'B', y: 30 },
{ x: 'C', y: 50 }
]
}
]
};
const divStyle = {
maxWidth: '700px',
height: '400px',
margin: '0px auto'
};
export default class SimpleChartComponent extends React.Component {
render() {
return (
<div style={divStyle}><JSCharting options={config} /></div>
);
}
}
This line chart example binds the chart to the components state. With this setup you can call the
component setState()
function to update the chart. See the Updating Chart section
for more information on using the mutable
option.
import React from 'react';
import { JSCharting } from 'jscharting-react';
const config = {
type: 'line',
series: [
{
points: [
{ x: 'A', y: 50 },
{ x: 'B', y: 30 },
{ x: 'C', y: 50 }
]
}
]
};
export default class SimpleChartComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
options: config,
mutable: false
};
}
render() {
return (
<div><JSCharting options={this.state.options} mutable={this.state.mutable} /></div>
);
}
}
JSCharting with TypeScript
The following area chart example demonstrates how you can use the JSCharting declarations for code completion in TypeScript (.tsx) files.
import * as React from 'react';
import { JSC, JSCharting } from 'jscharting-react';
const config: JSC.JSCChartConfig = {
type: 'area',
series: [
{
name: '2020 Sales',
points: [
{ name: 'Jan', y: 196 },
{ name: 'Feb', y: 178 },
{ name: 'Mar', y: 169 },
]
}
]
}
export default class typeScriptComponent extends React.Component {
render() {
return (
<div><JSCharting options={config} /></div>
);
}
}
You can check out the radar example in the examples/
react application which uses Typescript and the declarations file.
JSCharting Component Options
These configurable options are available with the JSCharting
component.
| Parameter | Type | Description |
| --------- | :----: | ----------- |
| options
| object | JSCharting chart configuration object. Please refer to the API documentation. |
| mutable
| boolean | (Optional) When set to true, chart.options()
is called with the updated props instead of recreating the chart object.
| callback
| function | (Optional) Function that is called when the chart is finished rendering. The first argument of the callback function is a reference to the created chart.|
| ignoreStateUpdate
| boolean | (Optional) false
by default. When true
, the chart will ignore updates applied when setState() is called. This is useful when you want to update the chart directly and use setState()
for other elements of the component. |
| className
| string | (Optional) Applies the class name to the chart container div element. It allows controlling chart size and layout with external CSS. |
Updating charts
There are a couple ways to update live charts.
Using setState()
The setState()
chart updates operate in two modes. When the component option mutable
is true, only new options set
through the setState()
function are passed to the chart using chart.options(). When mutable
is false, setState will
reset the chart with a new instance.
Charts with mutable == true
option perform better and allow charts to animate changes. Only new options that are changing
need to be passed to the chart. You can animate chart updates using this more.
Using mutable == false
is sometimes useful when a chart must be drastically modified. In this mode, all options should be
available in the state object for a new chart instance to use.
See animating series and points for more information.
export default class setStateUpdateComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
mutable: true,
options: {
series: [
{
name: 'Purchases',
points: randomPoints()
}
]
}
};
this.updateData = this.updateData.bind(this);
}
updateData() {
this.setState({
options: {
series: [
{
name: 'Purchases',
points: randomPoints()
}
]
}
});
}
render() {
return (
<div style={divStyle}>
<JSCharting options={this.state.options} mutable={this.state.mutable} />
<button onClick={this.updateData}>Update Data</button>
</div>
);
}
}
Bypass setState() - Updating chart directly
JSCharting has a rich API for interacting with chart elements programatically. this approach is more flexible and can update the chart more efficiently when performance is a priority. Charts can also be decoupled from setState updates and managed independently.
Set the ignoreStateUpdate
option to true when you want to use setState()
for other purposes but not affect the chart itself.
See getting a chart reference. Once a chart reference is available, you can update chart options as needed with code such as:
chart.series().points(p => p.y > 50).options({ color: 'red' });
This line will make all points on a chart with y values greater than 50 red. Another example:
chart.series(0).points(0).options({ y: 100 });
This selects the first point in the first series and changes the point's y value to 100.
In contrast, the setState()
method with mutable==true
can only call chart.options()
.
export default class directUpdateComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
mutable: true,
options: {
series: [
{
name: 'Purchases',
points: randomPoints()
}
]
}
};
this.chart = React.createRef();
this.updateData = this.updateData.bind(this);
}
updateData() {
const chart = this.chart.current && this.chart.current.instance;
if(chart){
chart.series('Purchases').options({points: randomPoints()})
}
}
render() {
return (
<div>
<JSCharting ref={this.chart} options={this.state.options} mutable={this.state.mutable} />
<button onClick={this.updateData}>Update Data</button>
</div>
);
}
}
Chart resources
The JSCharting library includes resources (modules, mapping data, polyfills, icons library) that load automatically
when they are needed. The examples webpack build copies these resources to the ./dist/jsc/
folder.
The examples app component examples/src/components/app.component.jsx
file calls the JSC.defaults()
function to set baseUrl
option with this path globally in
its constructor. All subsequent charts will be aware of the location of these resources.
import { JSC } from 'jscharting-react';
JSC.defaults({ baseUrl: 'dist/jsc', debug:true });
Note: If the chart does not find the resources path, it will download them from a CDN.
Setting debug:true
in the JSC.defaults()
function during development is recommended as it will alert you when the
CDN fallback is used. It is recommended to use a local copy of resources in production.
Getting a chart reference
You can get a chart instance using the React.createRef
method:
export default class LiveDataLineComponent extends React.Component {
constructor(props) {
super(props);
this.chart = React.createRef();
}
render() {
return (
<div style={divStyle}>
<JSCharting ref={this.chart} options={config} />
</div>
);
}
}
You can also store it when a chart callback function is executed.
export default class LiveDataLineComponent extends React.Component {
constructor(props) {
super(props);
this.chartCallback = this.chartCallback.bind(this);
}
chartCallback(chart){
this.chart = chart;
}
componentDidMount() {
// Using the chart reference.
this.chart &&
this.chart.series.add({ name: 'S1', points: [{ x: 5, y: 10 }, { x: 5, y: 10 }] });
}
render() {
return (
<div style={divStyle}>
<JSCharting options={config} callback={this.chartCallback} />
</div>
);
}
}
JSCLabel Component
This plugin also contains an implementation of the JSCLabel
component for react.
It can be used to create very efficient microchart SVG images in your react projects.
Here's a simple example.
import { JSCLabel } from 'jscharting-react';
export default class MicroChartComponent extends React.Component {
render() {
const data = [5,2,3,5,1];
return (
<div>
<JSCLabel options={`<chart arealine data=${data} width=200 height=50>`} />
</div>
);
}
}
See the microcharts tutorial for configuration syntax and more information.
JSCGrid Component
The JSCGrid
data grid component is also included. You can use it to to create data grids from JSON arrays.
Here's a data grid example.
import React from 'react';
import { JSCGrid } from 'jscharting-react';
export default class DataGridComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
options: {
data: [
['Art', 5, 10],
['Greg', 3, 6],
['Olivia', 11, 8],
['Steve', 11, 4],
['Anna', 3, 8]
],
columns: [
{ header: 'Name' },
{ header: 'Value One' },
{ header: 'Value Two' },
{ header: 'Sum', value: '{%1+%2}' }
]
}
};
}
render() {
return (
<JSCGrid options={this.state.options} />
);
}
}
The available options for the data grid component are.
| Parameter | Type | Description |
| --------- | :----: | ----------- |
| options
| object | JSCGrid configuration object. Please refer to the API documentation. |
| mutable
| boolean | (Optional) When set to true, grid.options()
is called with the updated props instead of recreating the grid instance.
| callback
| function | (Optional) Function that is called when the grid is finished rendering. The first argument of the callback function is a reference to the created grid.|
| className
| string | (Optional) Applies the class name to the grid container div element. It allows controlling grid size and layout with external CSS. |
See the data grid tutorial for configuration syntax and more information.
