After an operation is selected, the SELECT CURVE dialog box as illustrated in Figure 11.12.18 is displayed. The user can select a curve by choosing from those displayed in the curve window, selecting from the name list, or selecting the ALL CURVES button. eta/DYNAFORM prints the following message in the message prompt window:
LEFT BUTTON SELECT, MIDDLE BUTTON DESELECT
Figure 11.13.18 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. At least two curves must be selected.
Create
a new curve of which the values are the differences of two selected curves.
Create
a new curve of which the values are the product of two curves.
Create
a new curve of which the values are quotients of two selected curves.
Create
a new curve that is the derivative of the selected curve with respect to time.
Create
a new curve that is the 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.
ERASE
This function is used to remove the selected curve from the displayed graph
KEEP IN DATABASE
This function is used to save the selected curve in the database with a name that begins with CUR.
SAVE TO FILE
This function is used to save the display graph as a text file in a directory. The SAVE CURVE window is shown in Figure 11.13.19.
