12.3. - 2d, 3d select data exchange mode
sets how the fit data points will be exchanged with the C-PLOT data points.
2d 3dTwo sets of data points are maintained: those used for fitting and those exchanged with C-PLOT and used for plotting. When the fit is configured for more than one independent variable, these commands affect how the fit data points are assigned to C-PLOT data when using the
md, mr and
ps commands and how
the C-PLOT data is assigned to the fit data
with the
pg command.
If the fit is configured with only one independent variable, only 2D exchange mode is available.
In 2D exchange mode, the default independent variable for transferring data for the
pg, ps, md and
mr commands is
x1.
To use a different variable, specify its number on the
command line.
The
ps, md and
mr commands set C-PLOT
x,
y
and possibly (with
mr and
ps) y
error-bar values -- C-PLOT
x
error
bars are set to 0.
For the
pg command, only values for one independent
variable are read in.
The values of the other independent variables,
if any, are left unchanged.
When there is more than one independent
variable, the
md command increments each from the entered starting
value to the entered finishing value.
In 3D exchange mode, the default independent variables for exchanging data are x1 and x2. To use different variables, specify their numbers on the command lines to
pg, ps, md and
mr .
The
ps, md and
mr commands set the
C-PLOT
z
data from the fit dependent
variable.
For the
md command, you can set the range and the
number of intervals for the two independent variables to be transferred
to the C-PLOT
x
and
y
data.
You
enter constant values for any other independent variables.
Depending
on the ranges and number of intervals give for the independent variables,
the trajectory in the
x
-
y
data sent to C-PLOT
can form a grid or a line.
When making a grid of data, line-control
information is added to that data so that when the data points are
drawn with
lc mode on and a line symbol selected, the line will
be restarted each time
y = ymin.
