Pointer Annotation
An annotation for a category plot that displays a text item and an arrow pointing towards a point on a chart defined by a Category, Value pair.
Example of a pointer annotation:
Properties
Property | Name | Type | Description |
Category | category | String | Category key for the annotation. |
Category Anchor | categoryAnchor | String | Category anchor point, which helps to determine the position of the alignment point for the annotation |
Font | font | Data Table | Font used to display the text. |
Paint | paint | Data Table | Paint used to draw the text. |
Rotation Anchor | rotationAnchor | String | Text anchor point about which any rotation is performed. |
Rotation Angle | rotationAngle | Float | Rotation angle (in degrees). |
Text | text | String | Text displayed by the annotation. |
Text Anchor | textAnchor | String | Anchor point for the text. This will be aligned to the Category, Value point on the chart. |
Value | value | Float | Value that determines the alignment point for the annotation. |
Angle | angle | Float | Angle of the pointer (in degrees). |
Arrow Length | arrowLength | Float | Length of the arrow head. |
Arrow Paint | arrowPaint | Data Table | Paint used to draw the arrow. |
Arrow Stroke | arrowStroke | Data Table | Stroke used to draw the arrow. |
Arrow Width | arrowWidth | Float | Width of the arrow head. |
Base Radius | baseRadius | Float | Distance from the anchor point to the base of the arrow. The difference between the Base Radius and the Tip Radius is the overall length of the arrow. |
Label Offset | labelOffset | Float | Offset from the base of the arrow to the label. |
Tip Radius | tipRadius | Float | Distance from the anchor point to the tip of the arrow. Since the tip of the arrow is pointing towards the anchor point, this should be a lower value than the Base Radius. |
