Adding text to a figure - MATLAB - matlab

Question

I wrote a code that shows a figure devided to 2 parts;
the first one showing the main image, and the second one is a slider showing the rest of the images.
Now I need to add text to the main part (Like "Help" or "guide" text).
How can I do it?
This is my main sub-code:
%# design GUI
numSubs = 10; % Num of sub-images.
mx = numImgs-numSubs+1;
hFig = figure('Menubar','none');
% The Main Image:
hAx = axes('Position',[0 0.3 1 0.8], 'Parent',hFig);
hMainImg = imshow(img, 'Parent',hAx);
% the slider
hPanel = uipanel('Position',[0 0.04 1 0.26], 'Parent',hFig);
uicontrol('Style','slider', 'Parent',hFig, ...
'Callback',#slider_callback, ...
'Units','normalized', 'Position',[0 0 1 0.04], ...
'Value',1, 'Min',1, 'Max',mx, 'SliderStep',[1 10]./mx);
subImg = zeros(numSubs,1);
for i=1:numSubs
%# create axis, show frame, hookup click callback
hAx = axes('Parent',hPanel, ...
'Position',[(i-1)/numSubs 0 1/numSubs 1]);
% Load img number i
name=frames(i).name;
img=imread(name,'jpg');
subImg(i) = imshow(img, 'Parent',hAx);
value = i;
set(subImg(i), 'ButtonDownFcn',{#click_callback value})
axis(hAx, 'normal')
hold off;
end
Any suggestions?
Thanks in advance.

Use this construction:
hT = uicontrol('style', 'text', 'string', 'HELLO WORLD', 'position', [...])
It will create static text in the figure at position position. You can use all the regular options for uicontrols like 'parent' or 'units'.
However, since your image is in an axis, the better/easier way to do it is using
hT = text(X, Y, 'HELLO WORLD')
with X and Y the desired coordinates of the text in the axes.
You can set additional options via set:
set(hT, 'color', 'r', 'backgroundcolor', 'k', 'fontsize', 10, ...)
You can get a list of all options by issuing set(hT) on a mock text object.
