How to Real time IOT Dashboard with a sampling rate less than 1 second

Hello everyone

Is it posible to change the sampling rate of the dashboard to less than 1 second? Yesterdaw I saw a video of CMStick with thinger.io that changes this value to less than 1 second. The video is the following https://www.youtube.com/watch?v=r7RANgwbsfY.

Anyone can do a mini tutorial of how can i implement this or a brief explanation abaout that?.

Thank you
