How can I get a price from y coordinate, where the crosshair points?

[newtilus]

Hi there,

I struggle with one thing - how can I get a price from a specific y coordinate, not related to my series, from outside of the range? I would like to click on the chart and save the price selected by the user, which is different then the price on the chart.
I'm trying to use subscribeCrosshairMove and subscribeClick like below, but it will only give me the price range of the actual candle in the x position. Not the price from the pricescale of the y position. So in the example below I need to get 0,13 price, right where the crosshair is.

chart.subscribeClick((param) => { var price = param.seriesPrices.get(candleSeries); var coordinatePrice = candleSeries.coordinateToPrice(2); currentDataDiv.innerHTML = JSON.stringify(param)+" "+JSON.stringify(price); });

You can use https://tradingview.github.io/lightweight-charts/docs/api/interfaces/ISeriesApi#coordinatetoprice

For example

const series = chart.addLineSeries();
series.setData([ /* some data */ ]);

const myClickHandler = (param) => {
  if (!param.point) {
    return;
  }

  console.log(`The price is ${series.coordinateToPrice(param.point.y)}`);
}

chart.subscribeClick(myClickHandler);

Thanks for the answer, it works! I'm extremely surprise, as I thought that as it addresses the series, it will take the price from the series as well, not from the crosshair position! Cheers!

For future reference, maybe somebody will find it usefull, here's the updated code:

  chart.subscribeClick((param) => {
       var price = param.seriesPrices.get(candleSeries);
       var coordinatePrice = candleSeries.coordinateToPrice(param.point.y);
       log("The price is: "+coordinatePrice);
   });

ok with this function do I receive the price data in the coordinates? What if I need the time?
