DXCharts Lite: Powerful financial charting tool

DXcharts Lite is a modern solution for visualizing financial data with a wide variety of chart types.
Originally developed as part of large tradings applications used by millions of users,
DXcharts Lite has matured into an independent product.
It can be used as a simple widget for blogs or as a component in enterprise trading solutions.

Quick-start

Installation

Install the library in your project:

npm install @devexperts/dxcharts-lite

Your package.json after installation:

"dependencies": {
    "@devexperts/dxcharts-lite": "1.0.0",
    ...
}

Create chart

If you use webpack or another bundler, import the createChart method and pass the element where the chart will be rendered as the first argument.

export const createChartInstance = () => {
    const container = document.getElementById('chart_container');
    const chartInstance = DXChart.createChart(container);
    return chartInstance;
};

The createChart method creates a new chart instance using ChartBootstrap class and returns it.

It accepts two parameters:

• element: The HTML element where the chart will be rendered.
• config (optional): An instance of ChartConfig.

Note: Set width: 100% and height: 100% for the parent container. By default, the chart auto-resizes to the parent, but you can change this by setting fixedSize in the config.

You should now see an empty chart on the screen.

Set data

To display data (e.g. Candles), you can use the bundled function to generate mock data. Import generateCandlesData and use it to generate candles.

export const generateMockData = () => {
    const candles = generateCandlesData();
    chart.setData({ candles });
};

You should now see a basic chart like the image below:

HTML-markup

Here is complete quick-start code example:

<html>
    <head>
        <script src="https://www.unpkg.com/@devexperts/[email protected]/dist/dxchart.min.js"></script>
        <script type="importmap">
            {
                "imports": {
                    "@devexperts/dxcharts-lite/": "https://www.unpkg.com/@devexperts/[email protected]/"
                }
            }
        </script>
    </head>
    <body>
        <div id="chart_container"></div>
    </body>
    <script type="module">
        import generateCandlesData from '@devexperts/dxcharts-lite/dist/chart/utils/candles-generator.utils';

        // create chart instance, pass parent container as 1st argument
        const container = document.getElementById('chart_container');
        const chart = DXChart.createChart(container);
        // create and set candles data
        const candles = generateCandlesData();
        chart.setData({ candles });
    </script>
</html>

Configuration

You can configure the chart using a ChartConfig object (optional).

ChartConfig sets the initial properties for the chart instance. Below is a table of available options (see documentation for details).
