如何在轻量级图表 TradingView 中使用每小时和每分钟时间范围?
在示例中轻量级图表 TradingView 显示每日时间范围内的绘图,但我不知道如何正确地将数据传递给 setData 以便使用每小时和每分钟的时间范围。
请告诉我。
import { createChart } from 'lightweight-charts';
const chart = createChart(container);
const areaSeries = chart.addAreaSeries();
areaSeries.setData([
{ time: '2018-12-22', value: 32.51 },
{ time: '2018-12-23', value: 31.11 },
{ time: '2018-12-24', value: 27.02 },
{ time: '2018-12-25', value: 27.32 },
{ time: '2018-12-26', value: 25.17 },
{ time: '2018-12-27', value: 28.89 },
{ time: '2018-12-28', value: 25.46 },
{ time: '2018-12-29', value: 23.92 },
{ time: '2018-12-30', value: 22.68 },
{ time: '2018-12-31', value: 22.67 },
]);
const candlestickSeries = chart.addCandlestickSeries();
candlestickSeries.setData([
{ time: '2018-12-22', open: 75.16, high: 82.84, low: 36.16, close: 45.72 },
{ time: '2018-12-23', open: 45.12, high: 53.90, low: 45.12, close: 48.09 },
{ time: '2018-12-24', open: 60.71, high: 60.71, low: 53.39, close: 59.29 },
{ time: '2018-12-25', open: 68.26, high: 68.26, low: 59.04, close: 60.50 },
{ time: '2018-12-26', open: 67.71, high: 105.85, low: 66.67, close: 91.04 },
{ time: '2018-12-27', open: 91.04, high: 121.40, low: 82.70, close: 111.40 },
{ time: '2018-12-28', open: 111.51, high: 142.83, low: 103.34, close: 131.25 },
{ time: '2018-12-29', open: 131.33, high: 151.17, low: 77.68, close: 96.43 },
{ time: '2018-12-30', open: 106.33, high: 110.20, low: 90.39, close: 98.10 },
{ time: '2018-12-31', open: 109.87, high: 114.69, low: 85.66, close: 111.26 },
]);
In the examples Lightweight charts TradingView show plotting on a daily timeframe, but I can't figure out how to correctly pass data to setData in order to use hourly and minute timeframes.
Please tell me.
import { createChart } from 'lightweight-charts';
const chart = createChart(container);
const areaSeries = chart.addAreaSeries();
areaSeries.setData([
{ time: '2018-12-22', value: 32.51 },
{ time: '2018-12-23', value: 31.11 },
{ time: '2018-12-24', value: 27.02 },
{ time: '2018-12-25', value: 27.32 },
{ time: '2018-12-26', value: 25.17 },
{ time: '2018-12-27', value: 28.89 },
{ time: '2018-12-28', value: 25.46 },
{ time: '2018-12-29', value: 23.92 },
{ time: '2018-12-30', value: 22.68 },
{ time: '2018-12-31', value: 22.67 },
]);
const candlestickSeries = chart.addCandlestickSeries();
candlestickSeries.setData([
{ time: '2018-12-22', open: 75.16, high: 82.84, low: 36.16, close: 45.72 },
{ time: '2018-12-23', open: 45.12, high: 53.90, low: 45.12, close: 48.09 },
{ time: '2018-12-24', open: 60.71, high: 60.71, low: 53.39, close: 59.29 },
{ time: '2018-12-25', open: 68.26, high: 68.26, low: 59.04, close: 60.50 },
{ time: '2018-12-26', open: 67.71, high: 105.85, low: 66.67, close: 91.04 },
{ time: '2018-12-27', open: 91.04, high: 121.40, low: 82.70, close: 111.40 },
{ time: '2018-12-28', open: 111.51, high: 142.83, low: 103.34, close: 131.25 },
{ time: '2018-12-29', open: 131.33, high: 151.17, low: 77.68, close: 96.43 },
{ time: '2018-12-30', open: 106.33, high: 110.20, low: 90.39, close: 98.10 },
{ time: '2018-12-31', open: 109.87, high: 114.69, low: 85.66, close: 111.26 },
]);

从文档中,我们看到了关于
时间类型:
顾名思义,BusinessDay 和工作日字符串似乎不适用于低于一天的时间范围,这就是为什么像
YYYY-MM-DD
这样的date
字符串可以工作,但是像YYYY-MM-DD HH:MM
这样的datetime
字符串则不然。您将需要使用UTCTimestamp
。注意:
UTCTimestamp
是以秒为单位的时间戳,而不是毫秒。From the documentation, we see this about the
Time
type:As their names suggest, BusinessDay and business day string don't seem to work for timeframes lower than a day, this is why
date
strings likeYYYY-MM-DD
work butdatetime
strings likeYYYY-MM-DD HH:MM
don't. You will need to useUTCTimestamp
.Note:
UTCTimestamp
is a timestamp in seconds, not milliseconds.这对我有用。
this works for me.
