Candle Chart in React Charts

Candle

The Candle series, similar to the Hilo Open Close series, is used to represent the low, high, open, and closing prices over time. It is commonly used in financial charts to visualize stock price movements.

To render a candle series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

1. Set the series type: Define the series type as Candle in your chart configuration. This indicates that the data should be represented as a candle chart, providing a detailed view of stock price fluctuations by displaying the high, low, open, and close values for each time period.

2. Inject the CandleSeries module: Inject the CandleSeries module into the chart’s services using <Inject services={...} />. The samples below also inject Category so the x-axis renders month labels correctly. Inject additional modules such as Tooltip, Crosshair, or Zoom if your scenario requires them.

3. Provide high, low, open, and close values: The Candle series requires five fields (x, high, low, open, and close) to accurately display the stock’s high, low, open, and close prices. Ensure that your data source includes these fields to create a detailed representation of stock price movements over time.

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName, high, low, open and close properties.

Hollow candles

Hollow candles in candle charts allow you to visually compare the current price with the previous price by coloring them differently. This is the default rendering mode (when enableSolidCandles is false). The candles are filled or left hollow based on the following criteria:

States	Description
Filled	Candlesticks are filled when the close value is less than the open value, indicating a price drop.
Unfilled	Candlesticks are unfilled when the close value is greater than the open value, indicating a price rise.

The candle color is determined by comparing the current closing value with the previous closing value. In hollow-candle mode, the candle body is filled or hollow based on the relationship between its own opening and closing values, as described in the table above. By default, the `bullFillColor` is set to **red** and the `bearFillColor` is set to **green**. To customize the colors, set the [`bullFillColor`](https://ej2.syncfusion.com/react/documentation/api/chart/seriesModel#bullfillcolor) and [`bearFillColor`](https://ej2.syncfusion.com/react/documentation/api/chart/seriesModel#bearfillcolor) properties on the series. ## Solid candles The [`enableSolidCandles`](https://ej2.syncfusion.com/react/documentation/api/chart/seriesModel#enablesolidcandles) property is used to enable or disable solid candles. By default, it is set to **false** (hollow candles). When set to **true**, the fill color of each candle is determined by its opening and closing values: * The [`bearFillColor`](https://ej2.syncfusion.com/react/documentation/api/chart/seriesModel#bearfillcolor) is applied when the opening value is less than the closing value (price rose during the period). * The [`bullFillColor`](https://ej2.syncfusion.com/react/documentation/api/chart/seriesModel#bullfillcolor) is applied when the opening value is greater than the closing value (price fell during the period).

## Empty points Data points with `null`, `undefined`, or `NaN` values are considered empty. By default (`Gap` mode), empty data points leave a gap and are not plotted on the chart. The behavior can be customized using the [`mode`](https://ej2.syncfusion.com/react/documentation/api/chart/emptyPointSettingsModel#mode) and [`fill`](https://ej2.syncfusion.com/react/documentation/api/chart/emptyPointSettingsModel#fill) properties of `emptyPointSettings`. **Mode** Use the [`mode`](https://ej2.syncfusion.com/react/documentation/api/chart/emptyPointSettingsModel#mode) property to control handling of empty points. Available modes are `Gap` (leave a break, the default), `Drop` (ignores the empty point during rendering), `Zero` (plot as zero), and `Average` (plot as the average of neighboring points).

**Fill** Use the [`fill`](https://ej2.syncfusion.com/react/documentation/api/chart/emptyPointSettingsModel#fill) property to set the fill color for the empty candle. In the following sample, the empty candle is rendered in **blue** and its `open` value is computed using `Average` mode.

### Point render The [`pointRender`](https://ej2.syncfusion.com/react/documentation/api/chart/ipointrendereventargs) event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.
