B / M / K格式的TradingView自定义指标格式编号

Question

我正在使用TradingView（v 1.13），并实现了自定义UDF数据供稿。我正在将音量绘制为自定义指标。在custom_indicators文件中定义。我对如何格式化以B / M / K格式显示在y轴上的数字感到困惑。就像Chart Image中所示。我在文档中找不到任何内容。

这是我的小部件构造函数

var widget = window.tvWidget = new TradingView.widget({
                // debug: true, // uncomment this line to see Library errors and warnings in the console
                fullscreen: true,
                symbol: self.subject,
                interval: '15',
                container_id: "coins_trading_view_coin",
                datafeed: new Datafeeds.UDFCompatibleDatafeed(window.base_url,6000000),
                library_path: "/charting_library/",
                locale: self.getParameterByName('lang') || "en",
                indicators_file_name: window.base_url+"/charting_library/custom_indicators.js",

                disabled_features: ["use_localstorage_for_settings","header_compare","header_chart_type"],
                enabled_features: [""],
                charts_storage_url: 'https://saveload.tradingview.com',
                charts_storage_api_version: "1.1",
                client_id: 'tradingview.com',
                user_id: 'public_user_id',
                theme: self.getParameterByName('theme'),
                allow_symbol_change : false,
                hide_side_toolbar : true,
                overrides: {
                    "mainSeriesProperties.candleStyle.upColor": "#0C8912",
                    "mainSeriesProperties.candleStyle.downColor": "#C23A40"
                  },
                time_frames: []  
                });

这是我针对Volume的自定义指标配置

        name: "Trading Volume",
        metainfo: {
            "_metainfoVersion": 40,

                        "color": "#BFBFBF"
                    }
                },
                "precision": 1,

                "inputs": {}
            },
            "styles": {
                "plot_2": {
                    "title": "Volume",

                }
            },
            "inputs": [],
        },
