Normal mode: These commands mark the position (x,y) with the corresponding symbol. The size of the symbol is determined by the current value of the plot parameter marksize.

List mode: These commands mark the positions given by the vector expressions x, y1,... with the corresponding symbol. If no vector expressions are specified, all points of the list columns are marked. If the x-expression is omitted (i.e. if only a single expression, y1, is given), the x-coordinates are taken from the x-column of the list.
