Thank you, yes, your code works. My understanding in Matlab types, fields, cells ..and so on (and how to operate with them) is too small, i think - i hope my english is a litte better :) I have to learn more about all those things before going on.
Calling the LineWidth field brings 3 single answers, instead of an array (what i thought).
hAx.Children.LineWidth
ans =
0.5000
ans =
0.5000
ans =
0.5000
Edit: hAx.Children is a array of handles to graphic objects (Lines). Those Line-Objects each have a field LineWidth - and those are returned singly when using hAx.Children.LineWidth. Therefore i get 3 answers. Is that correct? And also therefore i cannot simple set them all at once by assigning a value to that structure field ..LineWidth ?
