How do I get the value of the candle I clicked?

[sumihiro]

I added a click event based on the graph of the next candle foot.
However, the value of the candle clicked cannot be taken.
How can I get a value?

svg.selectAll("g.candlestick")
.on('click', function(d,i,x) {
    console.log(d3.select(this).datum()); // will return all of values. I want a value of this item.
});

As for me, it turns out that it was easier to "write techan.js in d3" by myself. Seriously, it's not that hard.

I don’t understand you @episage How did you do it?

Sorry, I don't have time at this second to expand further, but the short of it is:

@icastillejogomez I learned https://d3js.org/ and wrote the code for drawing candles myself. It is not that difficult.
It took some significant time investment but it was worth it. Now I can draw very customised charts and techan.js doesn't limit me.
You can also modify techan.js code but I went the other way.

In this issue I can get the candle data that my mouse hover it. #226
