Large Data Set

Hi

I have an IoT device that sends a message to the storage once a min.

This would mean 1440 data points per day.

If I simply need to see plot the data a visual point of view can the data be compressed so that the datapoints are far less, but still shows the general plots data flow(High and lows)?

Re: Large Data Set

Hi djoshi,

Thanks for contacting us with your question.

That's exactly what data grouping does and sounds like it is what you're looking for in this case. Here you can read more about that functionality, its configuration options and see available examples:
https://www.highcharts.com/docs/stock/data-grouping

The option is enabled by default in stock chart and in case of any questions regarding it I am available at your convenience.

Regards!
