SHOW LOAD CURVE
This function enables the user to display the selected curve(s). In addition, the user can organize the display by using the options in the dialog window as shown in Figure 11.11.10.
Figure 11.11.10 The Show Curve Options Dialog Window
Select the load curve from the SELECT CURVE dialog window as shown in Figure 11.11.3.
LOCATION (SHOW CURVE)
. Toggle on FULL SCREEN to display the curve(s) in the display area.
. Toggle on USER DEFINED LOCATION and drag a window to display the curve(s).

QUERY
This function is used to display graph information using the following options:
. POINT
Select a point on a curve. Its X, Y coordinates will be given in the prompt window.
. CURVE
A list of defined curves appears. Select one from the list or choose from the screen. The name of the curve, number of points on the curve, the X range, and the Y range will be given in the PROMPT window.
. GRAPH
The name of the graph and the number of curves in the graph will be given in the PROMPT window.
OPTION FOR GRAPH DISPLAY
This allows the user to manipulate the display settings of AXIS, GRAPH, CURVE, GRID and LEGEND. See Figures 11.11.11 ~ 11.11.15.

This function allows the user to apply mathematical operations to the displayed curve. The options are shown in Figure 11.11.16.
Figure 11.11.16 Curve Operation
After an operation is selected, the SELECT CURVE dialog window will appear for selecting curves for the operation as shown in Figure 11.11.17. 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 prompts:
LEFT BUTTON SELECT, MIDDLE BUTTON DESELECT
Figure 11.11.17 Select Curve
Creates 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.
Creates a new curve of which the values are the differences of two selected
curves.
Creates a new curve of which the values are the product of two curves.
Creates a new curve of which the values are quotients of two selected curves.
Creates a new curve that is the derivative of the selected curve with respect
to time.
Creates a new curve that is the indefinite integral of the selected curve with
respect to time.
Scales
the selected curve using magnification factors in the X, Y directions.
Moves the selected curve
in the X, Y directions.
Creates a new curve that is a copy of the selected curve at the same position
and in different colors.
Negates the values of the selected curve in the Y direction.
Switches the X-axis and the Y-axis.
This function creates
a new curve that is the resultant of the selected curve.
Creates 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 loaded curves. The user needs to save the curve.
ERASE
This function removes the selected curve from the displayed graph
KEEP IN DATABASE
This function saves the selected curve in the database with a name that begins with CUR.
SAVE TO FILE
This function saves the display graph as a text file in a directory. The SAVE CURVE window is shown in Figure 11.11.16.
