SetAnnotationAttribute permits you to pass -1 in AnnotationIndex parameter to apply the attribute to all annotations on the graph, while SetCursorAttribute does not. It would be good that this command too permits someway to operate on all cursors in a single pass.
As an example, when I want to print a graph on a black-and-white printer I prepare the control for this changing all elements to black.
I can use a single instruction for annotations:
SetAnnotationAttribute (panelHandle, PANEL_GRAPH, -1, ATTR_ANNOTATION_CAPTION_COLOR, VAL_BLACK);
On the other hand, I need to iterate on all elements for cursors
GetCtrlAttribute (panelHandle, PANEL_GRAPH, ATTR_NUM_CURSORS, &numCursors);
for (k = 1; k <= numCursors; k++) SetCursorAttribute (panelHandle, PANEL_GRAPH, k, ATTR_CURSOR_COLOR, VAL_BLACK);
