    Arguments:

    fig: The figure object to which the Axes belong. We need this to set up

    Axes: The array of Axes object that we will plot on. Note that this

    Sol_NN: The network that approximates the PDE solution.

    PDE_NN: The network that approximates the PDE.

    Time_Derivative_Order: The order of the time derivative on the left-hand
    side of the PDE.

    Spatial_Derivative_Order: The highest order spatial derivatives of Sol_NN we
    need to evaluate.

    Data: This is a Data_Container object. It should contain four members (all
    of which are numpy arrays): x_points, t_points, Data_Set, and Noisy_Data_Set.
    x_points, t_points contain the set of possible x and t values, respectively.
    Data_Set and Noisy_Data_Set should contain the true solution with and
    without noise at each grid point (t, x coordinate). If t_points and x_points
    have n_t and n_x elements, respectively, then Data_Set and Noisy_Data_Set
    should be an n_x by n_t array whose i,j element holds the value of the true
