\chapter{Special Plot Text Capabilities} \label{appx:plt}
|
|
|
|
There are several special capabilities available for user-defined text
|
|
that appears on a plot (such as the plot caption). For example, the text
|
|
can include subscripted text, Greek letters, and special symbols. The
|
|
user requests a capability by inserting an ``escape sequence'' in the
|
|
text. The escape sequence starts with a backslash (``\verb|\|'') and
|
|
(unless otherwise noted) must end with a space which is
|
|
deleted from the text string. Escape sequences are translated only when
|
|
{\bf software} characters are plotted. If an invalid escape sequence is
|
|
entered, an error message appears when the plot is drawn and the
|
|
sequence is ignored.
|
|
The following escape sequences are available:
