How to find documentation on framewise and axiswise options

possibly a silly question, but how do I find the documentation for options like axiswise and framewise? It is not entirely clear what they do or how they are supposed to work. E.g. why does (some_scatter_plot.opts(framewise=True) * some_other_scatter_plot) work as if framewise is enabled (for the layout) when used in a DynamicMap, but (some_scatter_plot * some_other_scatter_plot).opts(framewise=True) doesn’t?
