Hi,

I've created a figure and annotated it using "text(x,y,'sample)" code, and I've got about 8 instances of it on my figure. I want to rotate all of these by 90 degrees since they're starting to overlap as I increase the axis ranges.

I'm hoping there's a way to grab the text object handles and then I think there's a text property that I can use 'rotate',90 to flip them all sideways.

SO the main question is, if I only wrote:

text(x,y,'sample')

rather than

text_handle = text(x,y,'sample)

does anyone know a way of grabbing the text object handles so that I can rotate them, without having to delete them and then re-do them? (I've lost their original positions).

Thanks.

Michael, The default rotation in text is 0°.

The text properties can be adjusted as the following example :

 plot(randn(100,1));
 h=text(1,1,'  My description');
 set(h,'Rotation',90);

hi, you have two ways :

1) use the data cursor in the 'tools' option in your figure to find the coordinates of the text written .

2)Use the findobj function to locate your text and then process it :

 Here is an example :
 plot(randn(10,4));
 text(1,1,'Random variables');
 % here i have no structure for the text, i locate it using :
 H=findobj(gca,'Type','text');
 set(H,'Rotation',60); % tilt
