如何使用 TradingView 轻量级图表中的新数据更新图表

Question

I am currently displaying an areaseries chart on a php page. The data gets populated during the initial page load which I fetch from database. Now I want to update the chart with duration, say for 1 week, 1 year etc. Couldn't find in the documentation as to how to delete the series or reload the chart with new data. I scoured the docs and github links but couldn't find what I was looking for.

Any pointers please.

if you use tradingview lightweight-charts library, you can use .update for example :

lineSeries.update(data)
candleSeries.update(data)
areaSeries.update(data)

The format of the data dictionary datas must be the same as the one you set them
