Is it possible to use a mouse to locate a position on a graph and then add user defined text. ideally using the mouse click callback?
Thanks Jason

t = linspace(0,2*pi,50);
y = sin(t);
plot(t,y) %Plot anything here, can be an image aswellm, whatever.
[x,y] = ginput(1); %Change the number if you want more than one text
str1 = 'test'; %This is the text displayed
text(x,y,str1) %Adds the text to the graph at x,y
Like this?
With more text:
t = linspace(0,2*pi,50);
y = sin(t);
plot(t,y)
str1 = {'Hello','this','is','Thomas!'};
[x,y] = ginput(length(str1));
text(x,y,str1)
