Dynamic graph link firebase data display (ios swift)

[michal.f]

I don't know what you want to set. Whether it will be a button or a switch depends on you.

If you do not know how to create elements such as a button/switch in Swift, then you need to read the documentation and API of Swift or seek help on forums related to Swift because this is not a problem related to Higcharts and it already goes beyond the scope of our support.

I want to use this chart function (swift) and the old data will not be deleted, and it will be updated every minute. Is there a way to do it?
and read the firestore data, how can I do it? Thanks a million

Hello,

The example you sent is a demo in pure JavaScript, with a basic knowledge of Swift you should be able to recreate it without any problems.

As I wrote recently in the message above, you are asking questions related mainly to Swift and not to Highcharts.

and read the firestore data

How to load data from FireStore in Swift is not a Highcharts question.

Regards!
