plot a discrete field (given as a FemField or by its coeffs in numpy or stencil format) on the given domain

Parameters:

numpy_coeffs(np.ndarray): Coefficients of the field to plot
VhTensorFemSpace: Fem space needed if v is given by its coeffs
space_kind(str): type of the push-forward defining the physical Fem Space
N_vis(int): nb of visualization points per patch (per dimension)

plot a list of scalar fields on a list of patches

Parameters:

title(str): title of the plot
vals(list): list of scalar fields to plot
titles(list): list of titles for each plot
xx(list): list of x-coordinates of the grid points
yy(list): list of y-coordinates of the grid points
