Y table
Y tables are based on the 'ST_PROF_YTAB' structure. They support the definition of a function y=f(x) with equidistant x axis resolution.
In the table structure, only the y values of the function y=f(x) are described.
The corresponding x values are generated in the block with 'uiNoElement'+1 equidistant points.
Thus:
|
A = |
udMasterInc |
| uiNoElement |
where A: equidistant spacing

Limiting to 'uiNoElement' = 360 is negated by mode 'enType' = PROF_YTAB_NL |

Advantages of the Y table
- High information density, as only the y values are saved
- Transparent presentation
Disadvantages of the Y table
- Points also have to be defined in sections with linear function characteristic
