6.4.1. - Plotting symbols
To use a numeral or one of the upper-case letters used as a code in the table above as the plotting symbol, precede it with a backslash,
\. If the characters
c or
z are used as symbols,
they must also be preceded with a \ because of their special meaning
to the key (see
gk, below).
To use any other character as a
plotting symbol, enter it as an argument to
sy or when prompted.
n-3i
Symbols, except for lines, may be inserted within text by using the four-character sequence
\[##, ##
is
00 for symbol 0 (a circle),
10 for symbol 10, etc.
Lines may be inserted into text using the three-character sequence
\*X, where substituting
A for
X
selects line-pattern
A (dotted),
B selects line pattern B (short dashed), etc.
The pattern length of dashed and dotted lines can be adjusted using the set parameter command described below.
