SHOW LOAD CURVE

This function enables the user to display the selected curve(s). Also, the user can organize the display by using the options in the dialog window CURVES, see Figure 9.11.10.

-SHOW LOAD CURVE

1. LOCATION

-SHOW LOAD CURVE

2. CLEAR

This function removes an object from the screen.

CURVE SCREEN

Clears all objects in the curve screen.

MODEL

Clears the displayed model.

ETA LABEL

Clears the label at the left bottom of the display screen.

ALL

Clears all objects in display screen.

3. QUERY

This function displays information about a graph in the curve screen.

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. The user can select one from the list or pick 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.

-SHOW LOAD CURVE

4. OPTION FOR GRAPH DISPLAY

This allows the user to manipulate the display settings of axis, graph, curve, grid and legend. See Figures 9.11.11 ~ 9.11.15.

Select the button to the right of OPTION FOR to select between AXIS, CURVE, GRAPH, GRID and LEGEND. Each option displays its own dialog window.

            

-SHOW LOAD CURVE

5. DEFINE RANGE OF GRAPH

This function zooms in on a specific section of graph.

-SHOW LOAD CURVE

6. OPERATION

This function allows the user to apply mathematical operations to the shown curve. The options are shown in Figure 9.11.16.

After an operation is selected, the SELECT CURVE dialog window will appear for selecting curves for the operation, see Figure 9.11.17. 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

 -- This function creates a new curve in the curve screen whose values of Y are the sums of the selected curves. At least two curves must be selected.

 -- This function creates a new curve whose values are the differences of two selected curves.

 -- This function creates a new curve whose values are the product of two curves.

 -- This function creates a new curve whose values are quotients of two selected curves.

-- This function creates a new curve that is the derivative of the selected curve with respect to time.

 -- This function creates a new curve that is the indefinite integral of the selected curve with respect to time.

 -- This function scales the selected curve using magnification factors in the X, Y directions.

 -- This function moves the selected curve in the X, Y directions.

-- This function creates a new curve that is a copy of the selected curve at the same position and in different colors.

 -- This function negates the values of the selected curve in the Y direction.

 -- This function switches X-axis and Y-axis.

-- This function creates a new curve that is the resultant of the selected curve.

Note: All results under the above operations are temporarily displayed in the curve screen. They will not be automatically saved as loaded curves. To keep the curve data, the user must perform either steps 8 or 9.

-SHOW LOAD CURVE

7. ERASE

Removes a selected curve from a displayed graph.

-SHOW LOAD CURVE

8. KEEP IN DATABASE

This function saves the selected curve in the database with a name beginning with CUR.

-SHOW LOAD CURVE

9. SAVE TO FILE

This function saves the display as a text file in a directory, see Figure 9.11.18.
