latexTherm creates a LaTeX picture environment for drawing a
series of thermometers
whose heights depict the values of a variable y assumed to be
scaled from 0 to 1. This is useful for showing fractions of sample
analyzed in any table or plot, intended for a legend. For example, four
thermometers might be used to depict the fraction of enrolled patients
included in the current analysis, the fraction randomized, the fraction
of patients randomized to treatment A being analyzed, and the fraction
randomized to B being analyzed. The picture is placed
inside a LaTeX macro definition for macro variable named name, to
be invoked by the user later in the LaTeX file using name
preceeded by a backslash.
If y has an attribute "table", it is assumed to contain a
character string with LaTeX code. This code is used as a tooltip popup
for PDF using the LaTeX ocgtools package or using style
tooltips. Typically the code will contain a tabular
environment. The user must define a LaTeX macro tooltipn that
takes two arguments (original object and pop-up object) that does
the pop-up.
latexNeedle is similar to latexTherm except that vertical
needles are produced and each may have its own color. A grayscale box
is placed around the needles and provides the 0-1 y-axis
reference. Horizontal grayscale grid lines may be drawn.
pngNeedle is similar to latexNeedle but is for generating
small png graphics. The full graphics file name is returned invisibly.
