Pictures are built up from data-, text- and key-elements. You can switch data elements ON or OFF as required. The ON state means that an element appears when the screen is REDRAWn, this being the default at the time of element creation. When switched OFF, elements still exist but are not displayed until switched ON again. The PLOT, BLB, DOT and COLOUR commands all switch the specified elements ON before drawing them. This does not apply to text or key elements, which can only be deleted or replaced, but cannot be switched ON or OFF.
The element-manipulation command has the following form:
ELEMENT <ON or OFF> <element number or range>
The element specification may be a single number, or a pair of numbers defining a range of elements.
You use the SHOW commands (see the Encyclopaedia entry) to list information about the elements that currently exist, including the element number and current state.
The DATA DELETE command erases the last element, whereas DATA CLEAR deletes all elements.
The command CLEAR deletes all elements (including text and keys if they have not been kept) for a fresh start.

EL[EMENT] AD[D] {dir} {i j}
The X (or Y , as specified by 'dir') coordinate of element j will be added to the X (or Y) coordinate of element i, and a new element will be generated. The Y (or X) coordinate will be that of element i. All arguments will be prompted for if not supplied.

EL[EMENT] DI[VIDE] {dir} {i j}
The X (or Y , as specified by 'dir') coordinate of element j will be divided by the X (or Y) coordinate of element i, and a new element will be generated. The Y (or X) coordinate will be that of element i. All arguments will be prompted for if not supplied.

EL[EMENT] MA[KE] {dir} {n} {i j}
This command makes a new data element by choosing a constant value of one coordinate, and then taking the values of the other coordinate at that location from a range of existing data elements. These values will be stored as the y axis, and the x axis will be numbered from 1 to the number of elements used.
Thus ; EL MA X 3 1 4 will take the y values from elements 1 through 4 inclusive, at the 3rd x location and store them as the new y. The x values will be 1,2,3,4. This feature is usefull when one has a number of data sets for different points in time, and one wishes to generate a time- history at a specific location. The element range i j may be specified as ALL. All arguments will be prompted for if not supplied.

EL[EMENT] MU[LTIPLY] {dir} {i j}
The X (or Y , as specified by 'dir') coordinate of element j will be multiplied by the X (or Y) coordinate of element i, and a new element will be generated. The Y (or X) coordinate will be that of element i. All arguments will be prompted for if not supplied.

EL[EMENT] OF[F] {i j}
Data elements in the range i to j are switched off. They will not appear on the screen after a REDRAW or SCALE command. If j is omitted, only element i is affected.

EL[EMENT] SUB[TRACT] {dir} {i j}
The X (or Y , as specified by 'dir') coordinate of element j will be subtracted from the X (or Y) coordinate of element i, and a new element will be generated. The Y (or X) coordinate will be that of element i. All arguments will be prompted for if not supplied.
