Does any one here have an idea about how to change the position of output in the GUI matlab to be to the right side of the box and not in the center ?
i think I have to change some properties of the result text box
Check this post out: Positioning of figures
The figure Position property controls the size and location of the figure window on the screen. Monitor screen size is a property of the root Handle Graphics object. At startup, the MATLAB software determines the size of your computer screen and defines a default value for Position. This default creates figures about one-quarter of the screen's minimum extent and places them centered left to right, in the top half of the screen.
The Position Vector
MATLAB defines the figure Position property as a vector. So you may use a figure and text into it, e.g.
figure(gcf)
text(offsetX1, offsetX1, ['result 1: ' num2str(result1)])
text(offsetX2, offsetX2, ['result 2: ' num2str(result2)])
Displaying analytical results in a MATLAB GUI
This post talks about adding a static textbox with your results and positioning it.
Move GUI figure to specified location on screen:
Syntax:
movegui(h,'position')
movegui(position)
movegui(h)
movegui
The answer is pretty much trying to cover up the vauge nature of the question

I used Matlab GUIDE to create a GUI.
It is displayed mid-screen.
How can I position it at the top of the screen; so that the top edge of the GUI window is at top of screen.
It will be used on different Windows 7 computers with different screen resolutions.
I tried to set hObject.Position(2) but it doesn't do what I want.
I think the simplest way would be to use movegui in the OpeningFcn of your GUI with the appropriate argument, i.e. using either 'north', 'northeast' or 'northwest'.
The calling syntax is quite simple, using the handles to the figure created. In GUIDE, the default name for figures is "figure1", so in your case the code would look like this (unless you changed the figure's name):
movegui(handles.figure1,'northwest') %// or whatever
Note that movegui calls the following 3 functions to get the screen size and monitor positions/units:
screensize = get(0, 'ScreenSize');
monitors = get(0,'MonitorPositions');
old0units = get(0, 'Units');
So you could do the same to make the calculations yourself in order to place the figure precisely where you want if the above solution is not sufficient for you.
I have a GUI which has 10 panel in it. My LCD is 20". When I want to see my GUI in my laptop(15.6") I can not see my Panels properly. I have examined all the solutions, but I can not solve this problem.
Can anyone help me?
To resize the figure just change its Position property. The panels will resize according to it, depending on how you specified your panel units. I.e., to maximize a figure:
set(figH,'Units','normalized');
set(figH,'Position',[0 0 1 1]);
In the case you want to specify your figure size as pixel units do:
set(figH,'Units','pixels');
set(figH,'Position',[left_gap_nPixels bottom_gap_nPixels length_nPixels width_nPixels]);
Btw, I haven't mentioned, but figH is your figure (or panel handle, if you want to resize it). You can use gcf if it is your current active handle.
Just as reference, the units you can specify are:
{'inches' 'centimeters' 'characters' 'normalized' 'points'
'pixels'}
Consider checking the figure properties documentation and uipanel properties for more details on the position and units property.
Hope it helps.
Take a look at property Units.
The size of a graphic object may be expressed in pixels, in characters, or better (for you) proportionally to the size of the parent.
If you change the units of the sizes of all the Panels to be proportional to the size of the main window, it will be ok. For the main window, simply use get(0,'ScreenSize'); to get the screen size in pixels.
I plotted few points using scatter and then label them using text. The position of these labels are same as the position of the points + some offset. Some of these text label overlap with each other and hence I moved them interactively (using mouse). I can check the new position of each of these text individually using property editor. However this is very time-consuming. Is there a better way to get the coordinates of all these text-label?
You can use findobj to get handles to text objects that are children of the current axes (or another handle... your choice):
text_handles = findobj('parent',gca,'type','text');
Then you can get the positions of these text objects:
positions = get(text_handles,'position');
You may need to do a bit more work to associate each text object with its data point - I suggest taking advantage of the property system, perhaps via the UserData field, for this, though there are many options.
If you want to do it easily later do this in your plots, for example:
h=text(2.9,7.5,'MyText');
This will put "MyText" at position 2.9, and 7.5.
Then to change the position use:
set(h,'Position',[2.5 7]);
This will change the position to 2.5 and 7.
Later if you need to see tthe position of text again use:
get(h);
Hope this helps.
As when you use subplot to display plots side by side in the same window, I would like a similar function that can do the same for multiple figures. This works:
subplot(2,2,1)
and I am looking for something like this:
subfigure(2,2,1)
Does a build-in function with this advantage exist?
You could write one such function yourself. The idea is to get the screen size:
get(0,'ScreenSize')
then divide it up into sub-regions according to the input parameters. You would also need to account for margins in-between.
Another idea:
create an invisible figure (preferably same aspect ratio as the screen)
call subplot inside it
capture the position of the created axis
delete figure
scale the position captured to fit the screen size, and use it to create the actual figures.
I have a question about the values returned by getPosition. Below is my code. It lets the user set 10 points on a given image:
figure ,imshow(im);
colorArray=['y','m','c','r','g','b','w','k','y','m','c'];
pointArray = cell(1,10);
% Construct boundary constraint function
fcn = makeConstrainToRectFcn('impoint',get(gca,'XLim'),get(gca,'YLim'));
for i = 1:10
p = impoint(gca);
% Enforce boundary constraint function using setPositionConstraintFcn
setPositionConstraintFcn(p,fcn);
setColor(p,colorArray(1,i));
pointArray{i}=p;
getPosition(p)
end
When I start to set points on the image I get results like [675.000 538.000], which means that the x part of the coordinate is 675 and the y part is 538, right? This is what the MATLAB documentation says, but since the image is 576*120 (as displayed in the window) this is not logical.
It seemed to me like, somehow, getPosition returns the y coordinate first. I need some clarification on this.
Thanks for help
I just tried running your code in MATLAB 7.8.0 (R2009a) and had no problems with image sizes of either 576-by-120 or 120-by-576 (I was unsure which orientation you were using). If I left click inside the image, it places a new movable point. It did not allow me to place any points outside the image.
One small bug I found was that if you left-click in the image, then drag the mouse pointer outside the image while still holding the left button down, it will place the movable point outside the image and won't display it, displaying a set of coordinates that are not clipped to the axes rectangle.
I'm not sure of what could be your problem. Perhaps it's a bug with whatever MATLAB version you are using. I would suggest either restarting MATLAB, or clearing all variables from the workspace (except for the image data im).
Might be worth checking to see which renderer you are using (Painter or OpenGL), a colleague showed me some wierd behaviour with point picking when using the OpenGL renderer which went away when using the Painter renderer.
Your code uses the Image Processing Toolbox, which I don't have, so this is speculation. The coordinate system is probably set to the figure window (or maybe even the screen), not the image.
To test this, try clicking points outside the image to see if you can find the origin.
