Hi,

I want to add a texbox to an existing figure (in code, not by tool) at a specified point (x,y). I try using

annotation('textbox',[x, y, .1, .1],'FitBoxToText','on')

but x,y need to be in normalized figure form, so I want to use ds2nfu(x,y), but in this function, x and y each specify a point (not x and y values..), and im not sure what to do..

What is the simplest way to (programatically) add a texbox to an existing figure at a specified point (x,y)?

thanks!

Asaf

one of the solutions

line(1:10,1:10);
ah=annotation('textbox');
% note: the position is set with respect to AH's own AXIS(!)...
set(ah,'position',[.4,.2,.4,.3]);
% - make the parent axis visible...
disp('cont with any key...');
pause;
ap=get(ah,'parent'); % <- is NOT GCA(!)...
set(ap,'visible','on');

Thanks so much for this; Im sorry, but I don't understand what the following part is meant for

> % - make the parent axis visible...
> disp('cont with any key...');
> pause;
> ap=get(ah,'parent'); % <- is NOT GCA(!)...
> set(ap,'visible','on');

and also, I feel that I don't get what you mean exactly with the ANNOTATION's own axis (vs whose? GCA's?...)

Last thing - I origianlly looked to specify the textbox's position with data points values (rather than normalized figure values..).

Thank you again,

Asaf
