Trend charts on the site map
Every channel on the site map has a trend chart. You can look back 24 hours, 7 days or 30 days.
The pictures in this guide use a sample dam project with sample data. Your own site image, nodes and readings will look different.

For other periods or your own analysis, export data from your gateway.
Try it yourself: open the site map in the Snape demo. It runs on a sample project, so nothing touches a real gateway.
