Hi, I want create realtime chart, so I update chart data frequently

When I update new data(ex, 200 data -> 201 data), zoom setting is initialized

I want fix zoom setting that were previously changed by the user

I already try updating example

Hi @Seongkyun-Yu, I'm trying to achieve the same.

How do you get the xExtents value from the zoom applied by the user?

@otaviobps

just fix xExtents value.

const xExtents = [min, max + 5] 

Even if data is added in real time, don't change min, max values.
