This article applies to version 4.5.4 and later of P2 Explorer. For the latest help, see Trace Table<\/a>.<\/p>\n

The Trace Table can be found below the trace window and the range selector, at the bottom of the trend.<\/p>\n

\"\"<\/a><\/p>\n

The trace table displays each trace item. Note that you can only add 20 items, and a warning message appears if you attempt to add more than this. You can configure your trace items by updating the table, and you can add or remove trace items in the table. Your selections are saved when you save the trend, and you can also save your selections to a snapshot of the trend.<\/p>\n

To adjust the height of the Trace Table, click and drag its top border.<\/p>\n

5. <\/strong><\/td>\nName<\/strong><\/td>\nThe trace Name<\/a> is a full display name of the item which is a tag, attribute value, or calculation. An attribute value could have an underlying value of a tag or a calculation.<\/p>\n

You can drag an item onto the trend, and the name will insert into a new row automatically. Or you can type a name in, using Auto-Complete<\/a>.
\n Click the calculator \"\" icon to edit the item in the Calculation Editor<\/a>; you can add a new calculation using tags, attributes and functions, or you can use the editor to edit an attribute value to use the \u2018entity\u2019 keyword to turn this into a templated trace item. Calculations can be used ad hoc, or they can be saved for use in other trends or on pages.<\/p>\n
