You can get at what you want with the following:

iPlot, findgen(10), findgen(10)^2

idTool = itGetCurrent(TOOL=oTool)

idAnnotate = oTool->FindIdentifiers('*/ANNOTATION LAYER')

oAnnotate = oTool->getByIdentifier(idAnnotate)

oAnnotate -> add, obj_new('IDLitVisText', _STRING='I wish there were a
manual that described this', ALIGNMENT=0.5, VERTICAL_ALIGNMENT=0.5,
FONT_SIZE=14, LOCATION=[0.5,0.8])

Note that the annotation layer uses normalized coordinates while the
visualization layer will use data coordinates. This means if you want
to add titles, legends or other floating objects, use the annotation
layer but if you want to output things that depend on the data (i.e.
print formatted text corrisponding to the x,y values for every 10th
data point) then you may be best to add IDLitVisText objects directly
to the visualization layer.

The above represents a general way of scripting iTools in that you
first locate the identifier from the tree with FindIdentifiers and then
either use a DoAction/DoSetProperty operation or grab the relevent
object. Beyond using the IDs and then finding the object, below are a
few other 'useful' commands that may be of use in your journey:

oWin = oTool->GetCurrentWindow()
oView = oWin->GetCurrentView()
oVisLay = oView->GetCurrentLayer()

You may want to poke around in:

$IDL_DIR/lib/itools/framework
$IDL_DIR/lib/itools/component

The above points to where the real documentation is ;)

Cheers,
Randall
