Charts support mouse and tap events. For all 5 charts, I implemented the zoom-in and zoom-out functionality. To switch the zoom you need to click on the pop-up, to fix the pop-up in one place during mouse events - click on the chart.
I want to convey my thanks. I really liked to participate in the event and I learned a lot of new things about myself and about the front-end development. Thank you Telegram Team.
Enjoy,
Nikita Kuznetsov.
