Currently multi-canonical, and grand canonical Monte Carlo simulations exist, but do not always give all of the necessary information of the system. When using a 1-D (only changing in one variable) broad histogram Monte Carlo method a user would need to run a range of simulations in order to get the data necessary for generating the equation of state. In our multi-grand, multi-canonical approach we demonstrate the effectiveness of a ``2-D" broad histogram simulation. The M-G, M-C Monte Carlo allows for both a change in the energy and the number of atoms in a square well fluid. The multiple degrees of change allow for the calculation of the entire equation of state from only one simulation.
