4. <\/strong><\/td>\nShow\/Hide Trace<\/strong><\/td>\nSelect to show the trace or clear to hide the trace.<\/td>\n<\/tr>\n
5. <\/strong><\/td>\nName<\/strong><\/td>\n\n

The trace Name<\/a> is the full display name of the tag, attribute value or calculation. An attribute value may have an underlying value of a tag or a calculation.<\/p>\n

Add an item name to the trace table by:<\/p>\n

6. <\/strong><\/td>\nDescription<\/strong><\/td>\nThe description from the underlying tag, or calculation.<\/td>\n<\/tr>\n
7.<\/strong><\/td>\nScan Rate<\/strong><\/td>\nShows the rate at which the source system stores raw data points; providing information as to why using certain tags may result in poor system performance.\u00a0<\/td>\n<\/tr>\n
8. <\/strong><\/td>\nValue<\/strong><\/td>\nThis shows the values for the respective items in the trace. If the trend has hairlines, then this is the current value from the latest hairline that was added or moved.<\/td>\n<\/tr>\n
\u00a0<\/td>\nDual Hairline Statistics<\/strong><\/td>\nThe Value<\/em> column changes to a drop-down list of Dual Hairline Statistics options, if the trend is in Dual hairline mode and if two hairlines are selected. Select from one of the following options:<\/td>\n<\/tr>\n
\u00a0<\/td>\n\u00a0<\/td>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
Time Weight Average<\/em><\/td>\nThe time weighted average calculated from the data between the two hairline positions<\/td>\n<\/tr>\n
Value Difference<\/em><\/td>\nThe value difference calculated from the values at the two hairline positions<\/td>\n<\/tr>\n
Time Difference<\/em><\/td>\nThe time difference between the two hairline positions<\/td>\n<\/tr>\n

Absolute Minute Integral<\/em><\/td>\nThe absolute integral between the two hairlines positions, calculated in minutes<\/td>\n<\/tr>\n
Absolute Hour Integral<\/em><\/td>\nThe absolute integral between the two hairline positions, calculated in hours<\/td>\n<\/tr>\n
Absolute Day Integral<\/em><\/td>\nThe absolute integral between the two hairline positions, calculated in days<\/td>\n<\/tr>\n
SI Integral<\/em><\/td>\nThe sample interval integral calculated from the data between the two hairline positions<\/td>\n<\/tr>\n
Absolute SI Integral<\/em><\/td>\nThe absolute sample interval integral calculated from the data between the two hairline positions<\/td>\n<\/tr>\n
Average<\/em><\/td>\nThe average of the data points defined by the two hairlines<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Note:<\/strong> The values and statistics in the trace table are calculated using the last known value before each hairline position, whereas the hairline information panel shows the interpolated value at the hairline position.<\/p>\n

This column only appears when the trend is in Time Series<\/em> mode.<\/p>\n<\/td>\n<\/tr>\n

To reset its minimum value as stored in IFS OI Server, click the \"\" on the right of the value. Clicking Auto Range<\/strong> on the trend ribbon updates all of the minimum and maximum values, so that all data points are visible on the trend.<\/td>\n<\/tr>\n
\u00a011.<\/strong><\/td>\nMax<\/strong><\/td>\nThe maximum value from the underlying tag or calculation's Display Range<\/em> (on IFS OI Server). Click in the box to edit the value.
