Webster's defines annotation as a "critical or explanatory notes added to a text." Using Khoros we are not so limited. We can add lines, circles, rectangles, and polygons of all sizes, as well as text. Anything we add to the graph may be moved at any time by clicking on it with the left mouse button and dragging the text/circle/line/rectangle/polygon to another area of the graph. We can manipulate the annotations in other ways as well.
Once you click on any
particular annotation, text or a shape, and click on Delete
button, the annotation will be erased. Do not worry about the graph
being altered.
Click on any annotation, and
then click on the Copy button, and you will receive
(surprise!) a copy of the annotation you chose. Click on the
left mouse button and drag it to the destination you had in mind.
This will raise the annotation
you clicked on before you clicked on the Raise button.
Note that this will not raise the graph above the annotation.
It will raise one annotation above another.
Like the Raise button, this
will Lower any annotation you choose. It will lower it beneath
another annotation, not the graph itself.
button.
If you have not saved annotations from a previous session with
xprism2, then I do not recommend trying to
write one from scratch. Save one from a session and then view it
with an editor. If you then feel confident enough to write one
on your own, don't say I didn't warn you. If you have saved
annotations, then by all means, bring them back if you think you
can use them. Remember again to put in the complete
address when entering the file name, and hit enter/return
once you have finished typing the address.

and you will see an extensive list of your choices. For this reason,
xprism2 allows you to use the `*' wildcard.
For instance, you may type in *adobe* in the Text
box, and the wildcards
will choose the first adobe font listed to be used in the annotation.
You may also try *helvetica-bold* which will use the
first `helvetica bold' type found in the list. Or, of course, you
may just leave the font in the fixed position. The Text
option is where you type in whatever explanation or commentary you
may have.
button and create your text!
Once you click on the Circle
button, you have the option of creating a filled or empty circle.
You also, as in the Text example,
have the option of placing the circle using the mouse or the keyboard.
If you use the mouse, then, in the graph, the first time you click on the
left mouse button, the circle will start to grow; the second time you
click the circle will stop growing. You may of course then
place it where you wish. If you use the keyboard to place the circle,
then you must enter in the center (x,y) and the edge (x,y)
coordinates.
The Rectangle option varies
little from the Circle. You may again choose to fill the rectangle,
and the placing may be done with the mouse or the keyboard. If you
use the mouse, the first click of the left button will start the rectangle
at one of the corners, and the second click will end the rectangle
at the diagonal corner. If you use the keyboard, you must enter in
the corner (x,y) and the diag (x,y) coordinates.
The Line option differs
slightly from the first two; you cannot choose to "fill" the
line. The placement options are the same: mouse or keyboard. The left
mouse button clicked once starts the line, and clicked a second time ends it.
The keyboard option must know the start (x,y) and the
end (x,y) coordinates.
The Polygon option is
the only one that must be entered with the mouse. You may
fill it if you so choose. Each click of the left mouse button (except
the one that starts the polygon) will complete one side of the shape.
To indicate that you are done making the polygon, double-click with the
left button.
