I am monitoring two lines that has a chance to collide from each other. The lines are represented through the XY Graph.
The user would like to see a "blinking" rectangle or square shape (depending on the lenght of the line) enclosing the line,
if collision is imminent. But if there is no collision, the rectangle or square shape will not be visible on the XY graph.
This is for the operators visual to check where is the collision might happen.
I attached a simple illustration of what i wanted to do.
1. How can I create the rectngle or suare shape figure if i am only given coordinates at the end points of the line?
2. How can i create the blinking property in the XY graph?
I would greatly appreciate for any help if above is possible.
Thanks a lot.
