The candle shows a line, no fluctuation, what to do?

[zbkmr]

I'm developing a vue js application. I added the chart to my app. When the page loads, I get the first data from the service and then update the data with the data from the socket. But on my chart the candles look like straight lines and there is no fluctuation.

Here you can find my data example.
data.txt

https://klinecharts.com/guide/faq There is a suggestion about this problem on the page, but I have no idea how to use it.
setPriceVolumePrecision(pricePrecision, volumePrecision)

When my chart is first opened, it looks like there is ripple, but when I zoom in it becomes a straight line.

here is the zoomed image

The candles should look like in this example.
