hi,
I want to use a cursor like fullcrosshair, but to have only
the horizontal line.
Is it possible to edit the pointer? if not, how can I make
a pointer with a full horizontal line?

thanks
german

It is possible. You need to look for the properties of the
figure, namely with something like:
set(gcf,'Pointer','custom','PointerShapeCData',something)
where something is explained in the manuals, and is where
you can freely use your creativity ;-)
Other property which might be worth investigating is
'PointerShapeHotSpot'

Look inside the setptr function for ideas/examples of how to
do this, as well as a few predefined cursor shapes that are
unavailable in set(gcf,'Pointer',...).

Note: setptr (and its sibling getptr) have been around in
Matlab for ages (at least since Matlab 5.3), but to this day
they are only partially documented (help text, but no doc)
and apparently unsupported. I really have no idea why:
Unlike moveptr (also semi-doc'ed, but which has a few quirks
and is still not ready for prime time), setptr & getptr
appear pretty stable and usable as-is.

hi
thanks for the reply.
custom pointers allow me to plot what I want but just in a
16 by 16 pixel scale. I need an horizontal line which will
extend through the whole x axis scale (similar to fullcross
hair, but without the vertical line).
setptr allow me to use more pointer designs but still
within 16 by 16 pixels scale.
do you have any ideas? where the fullcrosshair pointer
script is?

thanks
german

I have a File Exchange submission that does this - you can
copy & modify the relevant code from there: DataMatrix -

Did you manage to do it? I'm looking to do the same thing now.
