12.10. - md make data
generates points over a selected range, or one-to-one with your data, and sends the points to the plot program.
md [x [y]] [o] [p#=value ...]Without arguments, you enter starting and finishing values and the number of intervals as prompted by the fit program. Entering a literal
min or
max sets the starting or finishing value to the
data minimum or maximum.
Points are generated that will become the
plot program's current data.
If you include the
o argument,
you are not asked for a range and points are calculated at the current
values of the independent variables for each data point.
You can select which independent variable (if there is more than one) to send to the plot program by entering a value for
x
for transferring
2D data or values for
x
and
y
for transferring 3D data.
You also can set values for parameters using the
p#=value
notation, where the
#
represents the parameter number.
In 2D exchange mode, when there is more than one independent variable, each is incremented from the entered starting value to the entered finishing value. In 3D exchange mode, you set the range and number of intervals for two independent variables. Depending on the values entered, the trajectory in the x-y plane can be a line or a grid. In the case of a grid, line control information is added to the generated data, so that if drawn with
lc mode on and a line
symbol, the pen will be lifted between each
ymax and ymin.
Any other independent variables in 3D exchange mode are
held at constant values that you also can enter.
When running the fit as a stand-alone process, the generated points can only be used with the
sA command, described below.
