Disable magnify
in [Matlab]

From: Mano Samuel on 15 Jun 2010 21:58 Hello, Since this is my first GUI design, I have a few questions. One of them is, I found this interesting tool on MATLAB file exchange. http://www.mathworks.com/matlabcentral/fileexchange/5961-magnify it helps magnify a figure. So i added this to my GUI with the use of a 'checkbox'. The idea was that every time I click(mark a tick) on a checkbox in the GUI, I should be able to use this magnify function and if I remove the checkbox, I should not be able to use the magnify function. Now if I click on the checkbox, I am able to use the magnify function. However If i remove the tick mark, I am not able to disable the magnify function. Hoping someone can help me with this . How do I disable the magnify function ? Thanks

Hoping someone can help me out. Solved the above. Another question though. Given i have a GUI with a single graphic that displays an audio signal. What is the command to change the color of a portion of the signal. I think it has got be set(gcf(...........)) . I am not sure what command i need to use to fill in the blanks. Thanks.

I am not sure what command i need to use to fill in the blanks. Thanks. For ex, i can change the color of the entire signal by using, set(findobj('type','line'),'color',[1 0 0]) but not just a part of the signal .
