im not sure if this is possible but .....
in a nut shell i would like to overlay a variable size box/rectangle over a incoming signal (XY Graph)
to indicate to the user the area of signal being examined
my code will take in the user input (the x axis values range).
then draw a line up as far as the y value of the signal.
or a box or rectangle to show the user the area in question.
a shaded box would be cool but at this point im not that picky.
Any tips/pointers/ advice?

attached a quick sketch of what im trying to do.

Create a picture indicator witha transparent background. Draw a yellow rectangle on it in the size you need and move indicator to the position you need.
