ITEMCOUNT

Purpose:

Returns the number of columns in an item.

Syntax:

ITEMCOUNT(win, item)

win

-

Optional. Window reference. Defaults to the current Window.

item

-

Optional. A positive integer, the index to the item in the Window. Defaults to 1.

Returns:

An integer, the number of series (columns) that comprise the referenced item.

Example:

W1: gsin(100, .01)

W2: gcos(100, .01)

W3: xy(W1, W2)

 

itemcount(W3, 1)

 

returns the value 2. There are two columns in an XY plot.

Example:

W4: errorbar(W1+3*stdev(W1), W1+stdev(W1), W1-stdev(W1), W1-3*stdev(W1), 1)

 

itemcount(W4,1)

 

returns 4, the number of series that comprise an ERRORBAR series.

Remarks:

An ITEM is a data object comprised of one or more series. For example, an interval series is an item that consists of one series, an XY series is an item that consists of 2 series and an XYZ series is an item that consists of 3 series.

 

If the specified item number is larger than the number of items in the window, ITEMCOUNT returns 0.
