You will need to enable average trending for those parameters in the trend template. There are several ways to change your trend template (assuming you have the necessary security rights):

• In the element dropdown menu, go to protocols & templates => view trend template. You can do this from
  • Right click on an element
    or
  • Use the hamburger menu on the card (top left).
• Go to apps => protocols & templates and select your protocol and version.
• Drill down on your parameter, go to the templates tab.

Once average trending is enabled, the new parameter changes will be averaged every 5 minutes and every hour and added to the database. Once the records are old enough, you will be able to see more data than the last 24 hours.
