Display data on a trend chart

Display data on a trend chart

A trend chart displays data over time in a graphical format. Trend charts can display values from tags in a controller, user-defined properties, or properties of a graphic element. For example, a trend chart can monitor tank pressure and tank temperature over the course of an hour.
Use a trend chart to display data on a trace. Specify how data is displayed by setting the range of the data and how often the trend chart requests data.
View tag values from a data log on a trend chart by creating traces for the tags. Trend charts automatically display data from a data log for the specified tag. View the historical data on the HMI device by interacting with the trend chart.
Use a trend chart to:
  • Monitor processes in a manufacturing system
  • Display data from a tag, user-defined property, or the property of a graphic element
  • Display up to eight traces that plot data over time to graphically present data
  • View, pan, and pause data on the HMI device
