High Low Open Close Chart in Angular Charts

3 Feb 202624 minutes to read

High Low Open Close

To render an hiloOpenClose 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 HiloOpenClose in your chart configuration. This indicates that the data should be represented as a hiloOpenClose chart, which displays the high, low, open, and close values for each data point, providing a comprehensive visualization of stock price movements.

  2. Inject the HiloOpenCloseSeries module: Use the @NgModule.providers method to inject the HiloOpenCloseSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering hiloOpenClose series are available in your chart.

  3. Provide high, low, open, and close values: The HiloOpenClose 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.

Series customization

In the hiloOpenClose series, the bullFillColor property is used to fill the segment when the open value is greater than the close value, while the bearFillColor property is used to fill the segment when the open value is less than the close value. By default, bullFillColor is set to #e74c3d and bearFillColor is set to #2ecd71.

By default, bullFillColor is set as red and bearFillColor is set as green.

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

import { BrowserModule } from '@angular/platform-browser'

The pointRender 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.
