Figure 14.14.18 Select Curve dialog box
Create a new curve in the curve screen of which the
values of Y are the sums of the selected curves. Two or more curves must be
selected.
Create a new curve using the differences between two selected curves.
Create a new curve using the product of two selected curves.
Create a new curve using quotients of two selected curves.
Create a new curve that is derivative of the selected curve with
respect to time.
Create a new curve that is indefinite integral of the selected curve
with respect to time.
Scale the selected curve using magnification factors in the X, Y
directions.
Move the selected curve in the X, Y directions.
Create a new curve that is a copy of the selected
curve at the same position and in different colors.
Negate the values of the selected curve in the Y direction.
Switch the X-Axis and the Y-Axis.
Create a new curve that is the resultant of the
selected curve.
Create a new curve of which the abscissa is from
the first curve and the ordinate is from the second curve.
Note: All results under the above operations are temporarily displayed in the curve screen. They will not be automatically saved as load curves. The user needs to save the curve.
KEEP
IN DATABASE
This function is used to save the selected curve in
the database.
SAVE TO FILE
This function is used to save the display graph values as a text file in a directory. The Save Curve window is shown in Figure 14.14.19.
