If you mean that you want to change the pre-defined point markers take the
following actions:-
1. Click on one Data Point to highlight them all (or double click to
highlight just one).
2. Chart Tools / Format / Current Selection group / Format Selection /
Format Data Series pop up window should launch / select Marker Fill on the
left hand side / then Picture or texture fill on the right hand side / click
on File / select your sunflower file here / Insert / Close.
