How do I change color of a text in a given subplot?

225 views (last 30 days)
I have a given figure which contains 2 subplots. the first subplot has a text on it. I want to change the text color and size using set/get parent/children commands... I already have the handle to the line in the top subplot(which is the first subplot as well). how can I do that? Is 'text' a parent or a child off the line in the top figure?

you can change text color as follow:
x = -pi:.1:pi;
y = sin(x);
plot(x,y)
text(-pi/4, sin(-pi/4), '\leftarrow sin(-\pi\div4)', 'HorizontalAlignment','left', 'Color', 'r')
Or if you wanted to use set command then you can do it as follow:
h = text(-pi/4, sin(-pi/4), '\leftarrow sin(-\pi\div4)', 'HorizontalAlignment','left');
set(h, 'Color',[1, 0 ,0])

Iy you already have handler 'h' for object whose color and font property you want to set then use:
set(h, 'Color',[1, 0 ,0], 'FontSize', 20)
Which text you want to change in that figure? Is it title or xlabel or ylabel?
Also in order to find some specific object in figure you can use 'findobj'. See for more information:

there is just a text in the middle of the 1st graph... its not a title or axis lable! and I only have the handle to the line in the top subplot so I need to find the handle for the text object(also located in the top subplot) and change it, this is my main problam actually... I don't now even if a text object is a child/parent... and how to access its handle
thank you for your help :)
