Legend

Legend is a list of series and indicators at the top-left corner of any chart. Note that the legend position cannot be changed.

Legend

Configure legend​

In the Chart settings → Status line dialog, users can configure the legend.

Chart settings

Symbol logos​

If you want to display logos for symbols within the legend, follow the steps below:

  1. Enable the show_symbol_logos and show_symbol_logo_in_legend featuresets. The Logo option appears in the settings dialog.
  2. Provide URLs for symbols in the logo_urls property of the LibrarySymbolInfo object. Pass the object as a parameter to the callback of the resolveSymbol method.

Open market status​

By default, the library displays the current market status as an icon within the legend for the main series of the chart. You can hide the market status by adding the display_market_status featureset to the disabled_features array.

Title​

In the Title drop-down, users can select what title to display in the legend:

  • Description
  • Ticker
  • Ticker and description

You can also set the title using the Overrides API. For example, the code sample below sets ticker as the legend title.

chartApi.applyOverrides({ "mainSeriesProperties.statusViewStyle.symbolTextSource": "ticker" })

Last day change values​

info

Last day change can be displayed in Trading Platform only as it requires quote data.

Last day change is a parameter represented by two values: daily change and percentage daily change. You should specify these values in the ch and chp properties of DatafeedQuoteValues and pass them to the library when it calls getQuotes.

Last day change is displayed in Data Window on the right toolbar. You can also add this parameter to the chart legend using the overrides:

var widget = window.tvWidget = new TradingView.widget({
    // ...
    overrides: {
        "paneProperties.legendProperties.showLastDayChange": true,
    }
});

Users can toggle the Last day change values option in the Chart settings dialog to change the last day change visibility in the legend. This option is hidden by default. To display it, you should enable one of the following featuresets:

Resolution​

To disable resolution changing in the Legend, use the legend_inplace_edit featureset. If you want to completely remove the Resolution button from the Legend, use the hide_resolution_in_legend featureset.

Remove resolution from Legend

Visibility customization​

You can use featuresets or overrides to customize the legend's visibility such as hiding or displaying particular legend elements. The sections below describe customization via featuresets. For more information about override properties that affect the legend, refer to Legend.

Hide legend​

You can hide the legend widget from the chart. To do this, include the legend_widget featureset in the disabled_features array.

Disable legend

Hide legend buttons​

You can hide all legend buttons by including the edit_buttons_in_legend in disabled_features. Besides, disabling show_hide_button_in_legend, format_button_in_legend, or delete_button_in_legend allows customizing particular legend buttons. For example, the Settings button is hidden in the image below.

Hide context menu​

When right-clicking the legend, you can access the context menu. To disable this feature, include legend_context_menu in disabled_features.

Price formatting​

Prices are formatted according to the pricescale, minmov, minmove2, fractional, and variable_tick_size properties specified in the LibrarySymbolInfo object. For more information, refer to the Price format section.

You can also apply custom formatting using the numeric_formatting property of Widget Constructor.

new TradingView.widget({
    container: "chartContainer",
    locale: "en",
    library_path: "charting_library/",
    datafeed: new Datafeeds.UDFCompatibleDatafeed("https://demo-feed-data.tradingview.com"),
    symbol: "AAPL",
    interval: "1D",
    numeric_formatting: { decimal_sign: "," },
})

In the code sample above, the comma separates the decimal/fractional part of the price.

Numeric formatting

NaN values in legend​

If NaN values appear in the legend instead of the expected data, ensure that you have implemented the getQuotes and subscribeQuotes methods of the Datafeed API. This issue appears in mobile applications when running outside of tracking mode. Outside this mode, the legend shows only three values: the closing price, price change, and price change percentage. The library retrieves these values from the getQuotes request, otherwise, it displays NaN.

Note that open, high, and low prices and indicator values are displayed in the tracking mode only. To activate this mode, users should long tap on the chart. A single tap on the chart exits this mode.

Display delayed data information​

Follow the steps below to enable the Data is delayed section in the legend:

  1. Add the display_data_mode featureset to the enabled_features array of the Widget Constructor object.
  2. Provide the following properties in the LibrarySymbolInfo object. Pass this object as a parameter to the callback of the resolveSymbol method.
    • data_status – specify "delayed_streaming".
    • delay – specify delay in seconds.

The image below shows the Data is delayed section and the D icon in the legend.
