Does anyone know if I can make a horizontal and vertical scroll bar in a MATLAB GUI (not a list box)? Depending on the resolution of a computer it may or may not show all of the figure so I need to be able to scroll (horizontally in my case). How to do that?
This will create a figure with a horizontal scrollbar:
figure
plot(1:3);
b = uicontrol('Parent',gcf,...
'Style','slider',...
'Units','Normalize',...
'Position',[0,0,1,0.05],...
'min',0, 'max',1,...
'Value', 0);
However, if I were you, I would rather make sure the figure fits the screen and allow the user to zoom. Having a graph larger than screensize deprives the user from observing the entire graph at once.
You could
a) let matlab choose default figure size of the figure. Then the user can fullscreen if desired, or b)
screensize = get(groot,'Screensize');
figure('Position',screensize)
I hope this helps.

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 trivial question but not able find a effective solution. I hope somebody could help me in this regard.
I currently have 4 different axes in a GUI. ax1(top left) and ax4(bottom left) should be aligned vertically and similarly ax2(top right) and ax4(bottom right) should be aligned vertically. (I have attached a sample image)
ax1 and ax2 are used to show images that are usually larger in size(~512x512) and ax3 & ax4 are used to display images of size ~43x512. Even though I created the axes with x-axis the same size when I display images they change size and not aligned anymore. No matter what images I display, I want the top and bottom images to of same x length and aligned always.
I tried to keep the XLim the same; XData the same but still doesnt work.
Any help is greatly appreciated.
Thanks, Bala
You can use the align function which is used to do just that. The calling syntax is as follows:
align(HandleList,'HorizontalAlignment','VerticalAlignment')
Therefore in you case, you could write something like this (Note that you wrote ax4 twice in your question, I guess you wish to align axes 1-3 and 2-4):
align([handles.ax1 handles.ax3],'VerticalAlignment','none', 'HorizontalAlignment','center')
and likewise for the other 2 axes:
align([handles.ax2 handles.ax4],'VerticalAlignment','none', 'HorizontalAlignment','center')
I have a troubling problem that I've been trying to figure out for quite a while now and I just have no clue why it's happening. I have a self-coded GUI and I have a panel on the main GUI figure. On this panel I have an axes and whenever I plot a bar graph on that axes and try to edit its view with either yLim() or axis(), the axes will be resized to the dimensions I want, but the bar graph will not chop off at the edge of the axes and it will continue to run off the page. After playing around with it for a while in debug mode, I have found out that if I change the axes' parent from the panel it's on to the main figure, the bar graph will properly display only what is inside the axes borders like I want it to. I don't want to use changing the axes' parent as a permanent solution since I have several different panels I want to go between and having an axes on the main figure instead of the panel wouldn't work but I'd like to know if anybody knows why this is happening and how I can fix it.
For example, this code produces the problem I'm experiencing:
mainFig = figure('Units','characters',...
'Position',[40 5 200 50],...
'Color',[100/255 145/255 209/255]);
axesPanel = uipanel('bordertype','etchedin',...
'Parent',mainFig,...
'Title','Axes Panel');
mainAxes = axes('parent',axesPanel,...
'Units','characters');
bar(mainAxes,1:10,1:10)
ylim(mainAxes,[6 10])
And if the axes' parent is changed to be the figure, the problem doesn't exist. This line of code does that:
set(mainAxes,'parent',mainFig)
Thanks for any help or information as to why this is happening!
Just in case anybody else was having this same problem, I contacted MATLAB Technical Support and I was told that this was a bug on MATLAB's end that is being fixed in the next release(R2014b). They said that if you are having the problem I described in my original question, that in order to make the bar graph appear within the axes' boundaries at the moment, that you can edit the figure's 'Renderer' property and set it to either 'opengl' or 'zbuffer'. I have tested this and both options work so hopefully that helps :)
And just for extra clarification if it is needed, all I needed to change from my original code was:
mainFig = figure('Units','characters',...
'Position',[40 5 200 50],...
'Color',[100/255 145/255 209/255]);
To this:
mainFig = figure('Units','characters',...
'Renderer','opengl',...
'Position',[40 5 200 50],...
'Color',[100/255 145/255 209/255]);
And now the bar graph behaves as it should.
When I create a surface plot and use view([0 90]), so that I get a nice top-down view of the plot, the datatips are empty, i.e. the text is not visible. See the attached picture. As soon as I move the view a little bit they become visible though. Why is this happening and is there any fix?(1)
I don't really like the workaround to use view([0 90.0001]) instead. I'd rather see a fix than a workaround.
Mind that this doesn't happen when you save the file as a picture.
(1) It has probably something to do with heights. I think that the text height is at the exact same height as the box, which makes it possible that the text is drawn before the box, overwriting the text. I noticed that the box in that view sometimes disappears behind a surface which has a positive z-axis value.
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.
