Graphic presentation of the table 6

In the diagram 6

– the abscissae (x axis) represent the input values range, subdivided into sections.

– the ordinates (y axis) represent the output values with their color allocation.

Buttons 6

Å Accept

Click on the Accept button to save the settings. The option box will then close.

Å Cancel

With Cancel you can discard the settings. The option box will then close.

Å Help

With the Help button you can access explanatory material regarding the on-screen presenta-

tion.

Å Number input field

You can choose the number of sections

Å by entering the numerical value directly into the display field, or

Å by moving the scroll field in the scroll bar to the right or left using the mouse. In this way you

can run back and forth through the values range (1 - 5), or

Å by clicking on the lefthand or right-hand arrow on the scroll bar. In this way you can increase

or decrease the number of selections.

Programming the transformation table 6

Å Specifying the output values

Position the mouse pointer over the ends of the transformation lines of each section. The ends

are marked with small horizontal lines. A vertical double arrow will then appear on the screen.

Click on the lefthand mouse key and move the arrow upwards or downwards. This will move

the selected end of the transformation line and the numerical value will be displayed at OUT

Begin or OUT End.

Å Selecting the section limits

The graphical representation in Fig. 6.6 - 30 on page 280 shows equidistant section limits with

the ranges 0 - 80, 81 - 180 and so on. You can change these section limits if you wish. However

limits 0 and 255 are permanently allocated and cannot therefore be moved.

Position the mouse pointer on a section limit (but not 0 and 255). A horizontal double arrow will

appear on the screen. Hold down the lefthand mouse pointer and use it to drag the section limit

in the direction you want. The corresponding numerical value will be displayed at IN:.

Å Once you have programmed your transformation table you can quit the option box by clicking

on Accept or Cancel.

three following examples:
