Grid display using C++

My senior project partner and I need some help in programming a grid display using C++. A quick overview of our project: we are making a RF PET LEASH.
We are going to have 2 antennas which we will have fixed at 2 sides of a house and 3 transmitters doing their thing. The angles from the 2 transmitters to "Transmitter 3" (pet) will be the used to calculate the coordinates.

On the grid one of the antennas will be used as the zero axis and then there is the other one at a fixed distance away and then we have our "Transmitter 3" (x coord.) bopping away somewhere in the middle so ideally when "Transmitter 3" breaches the boundaries... we send out a warning signal.

So in one sentence "All the antenna's send data out to the pc, which parses them and displays it on the grid, calculating where the dot is and sounding an alarm when required."

We have a partial program right now that computes the coordinates of "Transmitter 3" and we would like to display this computed result relative to 2 fixed reference points on the grid. I did ask a few friends who are very familiar with C++ but it seems that grid/graph display is something they don't use or know much about.

Are there any specific books or websites you would suggest for this? Or better still do you know of a program that does something similar to this?

thanks in advance.

I understand that you need a visual representation of something you've a datastructure for? How to display this information then largly depends on what gui-toolkit you're using.

However, I've made the observation that most people who need somewhat more then ordinary spreadsheets tend to programm a their own representation on 2d or 3d canvanases like GDI or OpenGL.

Definitively you don't need a special library for this simple task. Just choose a C++ compiler and use simple primitive drawing functions (lines, points, etc.) to represent your grid and calculated point.
