Trend Config Tab

The Trend Config tab of Trend Properties contains options for configuring how the Trend will display tag data.

Default Timespan: Default timespan of the trend in hours (H), days (D), minutes (M) or seconds (S). Applies upon load or resetting timespan to default. There is a site-wide setting for the initial Default Timespan for new trend in System Configuration under System Defaults.

Normal Future %: Percentage of the plot area on the right reserved for future time. New data fills this space and when the trend line reaches the end of the trend, the X-axis shifts back, leaving this percentage of the screen available for new data. For example, with a value of 50, trend lines would build from the middle to the edge, then reset and build from the middle again.

Projected Timespan: The amount of time to show after the current time when Projected Data is enabled.

Absolute Start: Always loads the Trend with a fixed start date. This feature is useful for investigating a specific event in the past.
