Yes, I have seen, that the options are collected into a cell array
within the plot functions. However, keeping the options in a structure
has the advantage, that I can easily access and set the individual
options, e.g. to transform one plot template into a new one,  etc.
Also, how are graphic objects realized internally? Aren't they also
structures? It always seemed quite strange to me, that the get()
function returns a structure, while all the functions setting handle
options take lists of key, value,... as input arguments...
