proc catlines


Version 2.40 Jan'08

Scripts


Manual page for proc_catlines(PL)
proc catlines displays individual lineplots, one per category in X. Useful in comparing various entities, each of which have a displayable curve. New in 2.40

Plot data set must be ordered on category then subcategory.

Categories must be set up in X (based on catfield, see below), and a numeric axis in Y.


Attributes

catfield, subcatfield, valfield, and subcats attributes must all be specified.

catfield     dfield

A data field that contains primary category tags. This is the same data field that plot area X axis categories should be based on. There will be one curve drawn for each primary category.


subcatfield     dfield

A data field that contains secondary category tags. Secondary categories determine plot position within a given curve. Specify the set of allowable secondary categories in the subcats attribute.


valfield     dfield

A data field that contains the numeric plottable value.


subcats     list | auto

A comma-delmited or space-delimited list of allowable subcats, or else auto which causes the data set to be scanned to determine the list of allowable subcats at some performance penalty. The order found here determines the left-to-right plotting position.
Example: subcats: A B C
Example: subcats: auto


errfield     dfield

A data field that contains a numeric error bar value. Optional.. if omitted no error bars will be drawn. For example if valfield contains means, this field might contain SEM or SD.


plotwidth     h

Controls the plot region within the category space. Default is 0.6 which allows for a visible margin between primary categories. Increase this value to diminish the margin, or decrease this value to get a bigger margin.


select     select expression

Allows data rows to be selected for inclusion using a selection expression.
Example: @@2 = B


Appearance details

linedetails     linedetails

Color, line width, dash style for the drawn curves.

gapmissing     yes | no

Default is yes. If no, data points that are missing in any curve will be bridged. If yes, missing data points cause the curve to be interrupted.

dpsymbol     symboldetails

If specified, causes each data point to be marked with a geometric point symbol superimposed on top of the curve.

altsymbol     symboldetails

If specified, defines an alternate symbol to be drawn when altwhen condition is true.

altwhen select expression

A conditional expression that, if true, causes the altsymbol to be drawn instead of the dpsymbol.

errbardetails     linedetails

Color and line width for error bars, if any.

taillen     h

Size of error bar tails in inches (cm).
