This averages over a list galaxies to compute the average value of each attribute with errors, where the 1D regions within the errors are plotted as a shaded region to show the range of plausible models. Therefore, the input list of galaxies is expected to represent the probability density function of an inferred model-fit. This function makes a decomposed plot showing the 1D plot of each attribute for every light or mass profile in the galaxy, as well as their combined 1D plot. By plotting the attribute of each profile on the same figure, one can see how much each profile contributes to the galaxy overall. If the plotter has a 1D grid object this is used to evaluate each quantity. If it has a 2D grid, a 1D grid is computed from each light profile of the galaxy. This is performed by aligning a 1D grid with the major-axis of each light profile in projection, uniformly computing 1D values based on the 2D grid's size and pixel-scale. This means that the summed 1D profile of a galaxy's quantity is the sum of each individual component aligned with the major-axis. The API is such that every plottable attribute of the `Galaxy` object is an input parameter of type bool of the function, which if switched to `True` means that it is plotted.
