3.4. - eb select error-bar mode
turns error-bar mode on and off.
eb [x|y|z] [0|1]
Entered without parameters,
eb toggles error-bar mode on or
off.
In 2D mode it toggles
y-axis
error bars and in 3D mode
z-axis
error bars.
In 2D mode,
x or
y can be given
as arguments to toggle the respective error bars off or on.
An argument
of
0 or
1 will turn error bars off or on, respectively.
When a
? is entered with
eb, C-PLOT
will indicate which error-bar modes are on and which are off.
When switching between 2D and 3D plotting, the
y
and
z
error-bar modes will reflect each other's states.
For example, if
y
error bars are on in 2D mode,
z
error bars will be
on in 3D mode, and vice versa.
Although a file may include columns for error bars, C-PLOT
will not read them unless the error-bar mode has been turned on or
a nonzero column for the error bars has been specified under
gd modes 3, 5, 8 or 12.
When the error-bar mode is on, error bars are scanned in
gd modes 1, 2 and 11; error-bar values are displayed in
gd mode 7; error-bar values are included in the
save data
command,
sa; and error bars are drawn when you enter the
draw plot
commands,
p, pz, z
or
zz.
When the error-bar mode is on, the automatic data-ranging will include
the error bars in the range settings when the first data set is read
or when the
new points
command (np, see Chapter 5) is
used.
Data masking with
gd modes 4 and 5 will take error-bar
lengths into account when doing the masking.
