Customization overview

The library provides extensive customization options through multiple APIs. This overview article will walk you through customizing the chart's appearance and functionality.

Customization APIs​

  • Overrides. Customize elements on the chart like panes, scales, series, studies, drawings, and more.
  • CSS Styles. Customize UI elements outside the chart like toolbars, dialogs, and widgets.
  • Featuresets. Show/hide UI elements and modify chart interaction behavior. For example, you can enable the support of resolutions in ticks or disable chart scrolling.
  • Widget Constructor. Customize the chart size, list featuresets and overrides, set up a theme, and more.

UI elements​

Refer to the UI Elements section for more details on drawings, indicators, marks, and other elements.

Theme​

The library supports dark and light themes. Use the theme parameter in Widget Constructor to specify a theme. The default value is light. The chart layout does not contain buttons that switch the theme in the UI. Therefore, users cannot switch the theme unless you develop this option outside the library.

You should switch the chart's theme when the theme of your website changes. To do this, use the changeTheme method that changes the theme on the fly.

Note that the theme value is stored in the chart's configuration. Therefore, if you restore the chart that has the dark theme, you may see a black chart background in the light theme. In this case, you should apply the theme once again using the changeTheme method.

Language​

The library supports a variety of languages. For more information, refer to the Localization article.

The visibility of the TradingView logo depends on the terms of your license agreement. Contact your TradingView account manager for more information.

Price formatting​

Refer to the Price Format paragraph for information on how to customize the price format.

Non-customizable components​

The library doesn't support customization for the following components:

  • Icons on the toolbars

  • The color of some UI elements, for example, the TradingView trademark blue that appears in some dialogs

    Non-customizable Colors

Custom components​

The library does not support injecting custom UI components. If you want to add a UI component, implement it outside the library.
