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.
