3.2.5. - Modes 2 & 3: Reading data
Under mode 2, data will be read into the program from ASCII files -- created independently or using the
sa command described
below -- containing columns of
x
and
y
(in 2D mode)
and
z
(in 3D mode), plus, optionally,
r
(in 2D mode),
s
and
p.
Error bars will be read under mode 2 only if the
error-bar mode has been turned on using the
eb command.
Line-control
information will be read only if line-control mode has been turned
on using
lc. Under mode 3, you instruct C-PLOT which columns in the file to use to obtain values for x, y, z, r, s and p. If the columns for the error bars are set equal to 0, no values will be read in for r or s. If a nonzero value is entered for an error-bar column, values will be read in but error-bar mode will not be turned on. To enter a column for line-control values, you must first have turned on line-control mode with the
lc command.
Typing a
^C while reading from a file will abort the read, and
the number of points that were read will be reported.
