Re: high chart loading issue

Hello vandanamishra,

Welcome to our forum and thanks for contacting us with your question!

Here you can find demo with lazy loading example: https://www.highcharts.com/demo/stock/lazy-loading

General idea is to check if extremes changed and if so load additional data. Most likely you'll need to use afterSetExtremes event, exactly as in the example. Fetching / loading data logic you need to implement on your own.

Let me know if that was what you were looking for!
Best regards!
