Annotation List Property

Short Name: AnntList

Requires: Base Development System

Class: WaveformGraph Properties

To Use: Create a property.

Array of information about all annotations. Each array element is a cluster of annotation elements.

Elements

Name Description
Name The text displayed in the plot area that is associated with the annotation.
Color The color of the annotation, including its point, arrow, and name.
Style The symbol that, in combination with Point Style, is drawn at the focal point of the annotation. Valid values are 0-8, as shown on the Annotation Style shortcut menu item of the annotation from top-left to bottom-right.
Point Style The symbol that, in combination with Style, is drawn at the focal point of the annotation. Valid values are 0-16, as shown on the Point Style shortcut menu item of the annotation from top-left to bottom-right.
Name Visible If TRUE, displays the annotation name in the plot area.
Allow Drag If TRUE, allows you to drag the annotation.
Annotation Mode Specifies the way in which the annotation snaps to the plots in the plot area. Valid values include 0 (Free) and 1 (Single-plot).
Plot The plot with which the annotation is associated. If Plot is -1, the annotation snaps to all plots in the plot area. You can move the annotation to the nearest data point along any plot in the plot area. This element does not apply to free annotations.
Index The array index of the point to which the annotation is snapped.
Position:X The x coordinate of the annotation in the plot area. Position:X is in the coordinate system of the X Scale value that is associated with the annotation or plot.
Position:Y The y coordinate of the annotation in the plot area. Position:Y is in the coordinate system of the Y Scale value that is associated with the annotation or plot.
X Scale The x-scale associated with the annotation. This element applies only to free annotations and defines which x-scale is used with Position:X.
Y Scale The y-scale associated with the annotation. This element applies only to free annotations and defines which y-scale is used with Position:Y.
Show Arrow If TRUE, displays the arrow that points from the annotation name to the annotated data point.
Lock Name If TRUE, positions the annotation name absolutely so that when you move the annotation or scroll the plot area, the annotation name does not move in the plot area.
Plot Area The plot area with which the annotation is associated. This element applies only to mixed signal graphs with multiple plot areas.
Label Offset:X The X coordinate of the label position, relative to the annotation.
Label Offset:Y The Y coordinate of the label position, relative to the annotation.
