GraphSight is a convenient tool to plot and explore 2D math functions.
GraphSight has come as a realization of the idea: "A graph does not have to be dead". The program is based on the strong object-oriented concept by which every graphic object in GraphSight is a real interactive object and not a stark picture.
You may plot several functions in the same window, create several coordinate spaces defined by different variables (not only those y and x), set labels on the plot, use custom user-defined constants in every formula. All of the graphical objects on the plot are much interactive (i.e. they allow dragging, react to mouse clicking and moving).
GraphSight gives you a full control over a coordinate space, which can be shifted, and zoomed with the only help of mouse.
GraphSight is a project-oriented tool. A project is simply a document (.gs) you work with. A project can contain spaces (common 2D coordinate spaces) that are in their turn containers for graphic objects (graphs, labels, axes, etc.). GraphSight's Project tree provides you with a visual representation of a project and gives you a full access to all its properties. The program has good printing capabilities.
