The formula used to calculate a corresponding outcode is:

Functions have different arguments and outcodes. Those valid for one

function are not necessarily valid for another. See the

function reference

(page

111) for outcode specifications by function.

Example:

Suppose we want a Calculated Data function to display Percent Good,

Start Time, and Min/Max Time. Since Start Time and Min/Max Time are

displayed, the Show Timestamps bit must also be set. The function shown

on the Excel function bar would look like:

=PICalcDat("sinusoid","y","t","1h","minimum", 1,

325,"piserver")

If an outcode indicates a function should display multiple columns or rows,

but only one appears, right click and choose Recalculate/Resize to update the

function.
