Install library to your project:

"dependencies": {
"@devexperts/dxcharts-lite": "1.0.0",
...
}If you use webpack or any other bundler - import createChart method and pass element where the chart will be rendered as a first argument.
export const createChartInstance = () => {
const container = document.getElementById('chart_container');
const chartInstance = DXChart.createChart(container);
return chartInstance;
};createChart - method, that creates a new chart instance using ChartBootstrap class and returns it.
Method accepts 2 parameters:
element- The HTML element where the chart will be renderedconfig(optional) - instance of ChartConfig
Also, please, set
width: 100%andheight: 100%for parent container by default chart is auto-resizing to parent you can change it by settingfixedSizein config
Now you should have empty chart on screen.
Let's pass in some data i.e. Candles. You can use bundled function to generate some mock data.
Import generateCandlesData and call it to generate candles.
export const generateMockData = () => {
const candles = generateCandlesData();
chart.setData({ candles });
};Now you should see chart just like image below:
Here is full 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>You can configure chart with ChartConfig object. It is optional.
ChartConfig is used to set initial properties for chart instance.
Below you can see full table of it, and other options, that ChartConfig consists of.
Every chart component has an API allowing change a lot of params on the fly. Change appearance at runtime. Subscribe on different events in chart (like HOVER on candle)
Here are the links of the main components:
ChartComponent- set data, subscribe on data changesXAxisComponent- configure x-labelsYAxisComponent- configure labels and set y-axis typeCrossToolComponent- cross-hair type, OHLC magnetEventsComponent- set events dataVolumesComponent- set volumesWaterMarkComponent- create and manage a watermarkNavigationMapComponent- create a navigation mapSnapshotComponent- create a snapshotHighlightsComponent- allows to draw highlights of some canvas objects such as labelsPaneManager- create and manage panesPaneComponent- create and manage panes data series
