XYZSetHullNewDataΒΆ
XYZSetHullNewData creates a new data hull that can also contain islands.
-
bool = XYZSetHullNewData(hData, rvX, rvY, rvLineTo)
Return Value
If the function succeeds, the return value bool is TRUE (1); otherwise it is FALSE (0).
Parameters
-
hData The handle of a dataset created with XYZCreate.
-
rvX rvX A vector with the x-coordinates.
-
rvY rvY A vector with the y-coordinates.
-
rvLineTo rvLineTo A vector of characters which define the shape of the data hull, e.g. Full Load Line (WOT). Each vector element be one of the following ASCII characters:
| Value | Meaning |
|---|---|
"m" ASCII-Code = 109 |
MoveTo without z-value label. |
"M" ASCII-Code = 77 |
MoveTo with z-value label. |
"l" ASCII-Code = 108 |
LineTo without z-value label. |
"L" ASCII-Code = 76 |
LineTo with z-value label. |
Comment
All vectors must have the same number of elements. The z-value for the labelling of hull data points will be interpolated.
Example
rvHull = [10,10; 20,10; 20,20; 20,10];
nRows = nr(rvHull);
rvLineTo = zeros(nRows, 1) + 109; // MoveTo
XYZSetHullNewData(hData, rvHull[;1], rvHull[;2], rvLineTo);
XYZSetHullType(hData, HULL_USERDEF);
XYZUpdate(hData);
