I've started teaching myself sage and I'm a bit confused about the naming of some commands in graphics. The most basic command for graphics is perhaps plot with its variants polar_plot, contour_plot, etc. However, I've also seen some variants of plot that are obtained from plot by adding postfixes to it; for instance, plot_vector_field.
Does anyone know the reason why some graphical commands belong to the first category (prefix_plot) and some to the second (plot_postfix)? I'm asking this because of there is a good reason for this, then it can help me remember the names more easily, and if there is no special reason this might be something to suggest for changes in future releases of sage.
PS I asked this question on stackoverflow and got a suggestion for asking it here.
