Purpose
This property array is used to define horizontal line annotation types. Type 16 and over only work if RenderEngine is Hybrid or GdiPlus.
Note that horizontal line annotations will not be seen unless ShowAnnotations or ShowHorzLineAnnotations is set to TRUE.
The types of line annotations available are defined by the following constants:
|
.NET Gigasoft.Enums.
|
ActiveX and
|
|
|
LineAnnotationType.

Comments
PeAnnotation.Line.YAxisType members of Pego.PeAnnotation.Line, Pesgo.PeAnnotation.Line, Pe3do.PeAnnotation.Line, Pepso.PeAnnotation.Line
See Also: HorzLineAnnotation, HorzLineAnnotationText, and HorzLineAnnotationColor. If you want to legend an annotation, see LegendAnnotationType. If you are implementing multiple axes, see HorzLineAnnotationAxis.
Use PELAT_GRIDTICK and PELAT_GRIDLINE to construct your own custom scale. When PELAT_GRIDTICK and PELAT_GRIDLINE are used, HorzLineAnnotationText controls the location of the annotation text via a text justification code. Also, if you assign a color of (1) to these annotations, the current GraphForeColor will be used to color the annotation. This allows these annotations to function identically to normal grid lines and GridLineControl also controls the look of these annotations. You may also need to disable the default grid with ShowYAxis and generally set LineAnnotationTextSize = 100
You can define horizontal line annotations with respect to the right Y axis by adding 1000 to the above constants.
See Also: VertLineAnnotationType, GraphAnnotationType
Refer to Chapter 7, Question 10 for more information on annotations.
Within the demo, see example 101.
WinForm VB.NET Example
The following example shows how to add two horizontal line annotations, a thin line at 10, and a dashed line at 20.
|
Pesgo1.PeAnnotation.Line.YAxisType(0) = LineAnnotationType.ThinSolid
Pesgo1.PeAnnotation.Line.YAxis(0) = 10
Pesgo1.PeAnnotation.Line.YAxisText(0) = "Line1"
Pesgol.PeAnnotation.Line.YAxisType(1) = LineAnnotationType.Dash
Pesgo1.PeAnnotation.Line.YAxis(1) = 20
Pesgo1.PeAnnotation.Line.YAxisText(1) = "Line2"
|
OCX Example
The following example shows how to add two horizontal line annotations, a thin line at 10, and a dashed line at 20.
|
Pesgo1.HorzLineAnnotationType(0) = PELT_THINSOLID
Pesgo1.HorzLineAnnotation(0) = 10
Pesgo1.HorzLineAnnotationText(0) = "Line1"
Pesgo1.HorzLineAnnotationType(1) = PELT_DASH
Pesgo1.HorzLineAnnotation(1) = 20
Pesgo1.HorzLineAnnotationText(1) = "Line2"
|
C / C++ Example
The following example shows how to add two horizontal line annotations, a thin line at 10, and a dashed line at 20.
|
int nTypes[2];
double fYLoc[2];
char szText[] = "Line1\tLine2\t"; /* Code to define text */
/* Code to define line styles */
nTypes[0] = PELT_THINSOLID;
fYLoc[0] = 10.0F;
nTypes[1] = PELT_DASH;
fYLoc[1] = 20.0F;
PEvset (hWndPE, PEP_naHORZLINEANNOTATIONTYPE, nTypes, 2);
PEvset (hWndPE, PEP_faHORZLINEANNOTATION, fYLoc, 2);
PEvset (hWndPE, PEP_szaHORZLINEANNOTATIONTEXT, szText, 2);
