            format: (value) => (value / 1e9).toPrecision(format?.precision || 2) + 'B'
        };
    }

    if (format.type === 'percent') {

drawings_access​

Optional

You can hide some drawings from the toolbar or add custom restrictions for applying them to the chart.

This property has the same structure as the studies_access argument. Use the same names as you see in the UI.

Remark: There is a special case for font-based drawings. Use the "Font Icons" name for them. Those drawings cannot be enabled or disabled separately - the entire group will have to be either enabled or disabled.

Example

drawings_access: {
    type: 'black',
    tools: [
        {
            name: 'Trend Line',
            grayed: true
        },
    ]

Type​

​ChartingLibraryFeatureset[]

favorites​

Optional

Elements that should be marked as favorites for a new browser or user. You can use this property to specify default favorite chart types, drawings, indicators, and resolutions. To do this, assign a Favorites object to favorites. The example of such object is demonstrated below.

favorites: {
    intervals: ["1D", "3D", "3W", "W", "M"],
    indicators: ["Awesome Oscillator", "Bollinger Bands"],
    drawingTools: ['LineToolBrush', 'LineToolCallout', 'LineToolCircle'],
    chartTypes: ['Area', 'Candles'],
},

To allow users to add/remove items from favorites, enable the items_favoriting featureset.

Note that favorites saved in localStorage take precedence over the ones specified in the favorites property. Therefore, the library tries to load the favorites from localStorage first, and then use the elements in favorites if there is nothing saved in localStorage. If you want the elements specified within favorites to always apply, disable localStorage using the use_localstorage_for_settings featureset.

You can also use ChartingLibraryWidgetOptions.settings_adapter to store favorites. These favorites take precedence over favorites in the favorites property and localStorage. Refer to the Customization precedence article to learn more about the application order of different approaches for changing the chart appearance and behavior.
