Trendline does not draw correctly when out-of-view

Lightweight Charts Version: “lightweight-charts”: “^1.2.1”

Steps/code to reproduce: Not sure if this is considered a bug as this is a workaround for drawing trend-lines by overlaying two charts together.

When either the start or end point pans out of view, the overlay addLineSeries behaves rather ugly

const trade_overlay = tradeReportChartOverlay(pnl_line_color)
trade_overlay.setData([
    {value: entry_price, time: epoch_entry_time},
    {value: exit_price, time: epoch_exit_time}
])

Actual behavior: Please see image below on the resulting behaviour

Expected behavior:

Ideally it should be able to draw the trend line accurately On a side note, is it possible to remove the overlay addLineSeries data in the event the either the start or end “time” is “out-of-view”

Could you please clarify why do you set line series an overlay? I belive it should be bound to the same price scale as candles.

import {createChart, CrosshairMode, LineStyle} from "lightweight-charts";
const chart = createChart(elements.candlestickChart, {...})

const barSeries = chart.addCandlestickSeries({...})
const tradeDetailLineSeries= chart.addLineSeries({ overlay: true })

the barSeries has the full OHLC data, where as the tradeDetailLineSeries is limited to two points (which is the start- and end-point of the trendline)

Also, it would be very helpful to have jsfiddle-like repro.

Sure, I’ll try to port over an example this afternoon

Closing.
This was an bug on my side; It looked like the underlying ohlc was drawn with UTC, while the Trendline was draw with EST… so the trendline sort of fell-off when out of viewpoint
