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.
