help pvsel: Help for selecting paths for pvplot - 2009-10-11

Overview

pvsel is a command to select paths to be shown or hidden when
plotted.

Syntax

pvsel
[, options]

reset Reset current selections to none rather than adding
conditions to current selections.

all(cat#) Select path if all items are in this category.

any(cat#'s) Select path if it is ever in any of these categories.

and Add the current selection to existing selection criteria
as a logical "and". By default, new selections are added as an "or" condition.

hide If specified, conditions define paths to hide; by default
pvsel specifies paths to be shown.

test Run in test mode for debugging.

Note: "cat#" is a category number; "cat#'s" is a list of numbers.

Notes on using pvsel

You can use pvsel in sequence with pvplot to create a series of
graphs in which the selection is revised. For example:

. pvsel ... // initial selection
. pvplot ... // plot with initial selection
. pvsel ... // modify existing selection
. pvplot ... // plot revised selection
