(Updated - new issue) - Matlab - Displaying bar graph in GUIDE GUI Issue - matlab

This is the bar graph that I want to display on the GUIDE GUI. I put this code into the OpeningFcn function of the GUIDE GUI, and what essentially happens is that the actual box section dedicated to the graph (its tagged "axes1") appears in the GUI window, but then another Figure window appears displaying the bar graph. How would I go about placing this bar graph into the GUIDE GUI in the space dedicated to the box axes1?
I do not need any push button trigger to display it. The graph should appear in its dedicated spot on the GUIDE GUI when the GUI window is open.
EDIT: This is the graph data I want to display. I was using the previous one as an example so I could learn from it. However, for some reason there is a problem of the below graph appearing twice in the window - it appears once, closes, and then appears again. How would I fix it so it only appears once? All of this is under OpeningFcn and I don't have additional code under CreateFcn.
dbedit = matfile('varDatabase.mat', 'Writable', true);
results_pData = dbedit.pData;
results_uData = dbedit.uData;
results_name = dbedit.name;
% Create data for each set of bars for data from each group
% i.e. [participant, population].
% Population is defined as the previous user data stored in its full in uData.
expSingle = [((results_pData(1,2)/7)*100), ((mean(results_uData(:,2))/7)*100)];
expConjugate = [((results_pData(1,3)/7)*100), ((mean(results_uData(:,3))/7)*100)];
ctlSingle = [((results_pData(1,4)/7)*100), ((mean(results_uData(:,4))/7)*100)];
ctlConjugate = [((results_pData(1,5)/7)*100), ((mean(results_uData(:,5))/7)*100)];
% Create a vertical bar chart using the bar function
bar(handles.axes1,1:2, [expSingle' expConjugate' ctlSingle' ctlConjugate'], 1)
% Set the axis limits
axis([0 2.8 0 100])
set(gca,'XTickLabel',{results_name,'Population'})
% Add title and axis labels
title('Proportion of Responses for Conjunctive vs. Single Choices')
xlabel('Entity')
ylabel('Proportion of Responses (%)')
% Add a legend
legend('Single Choice, Experimental', 'Conjugative Choice, Experimental',...
'Single Choice, Control', 'Conjugative Choice, Control')
Input would be greatly appreciated.

That's because of your call to figure right after the creation of your data, which indeed creates a new figure outside of your GUI.
To solve your problem remove that line, and consider adding the actual axes handles in the call to bar:
bar(handles.axes1,1:12, [measles' mumps' chickenPox'], 1)
Therefore your whole code could look like this:
%Create data for childhood disease cases
measles = [38556 24472 14556 18060 19549 8122 28541 7880 3283 4135 7953 1884];
mumps = [20178 23536 34561 37395 36072 32237 18597 9408 6005 6268 8963 13882];
chickenPox = [37140 32169 37533 39103 33244 23269 16737 5411 3435 6052 12825 23332];
%Create a vertical bar chart using the bar function
%// Remove the call to figure.
bar(handles.axes1,1:12, [measles' mumps' chickenPox'], 1)
% Set the axis limits
axis([0 13 0 40000])
set(gca, 'XTick', 1:12)
% Add title and axis labels
title('Childhood diseases by month')
xlabel('Month')
ylabel('Cases (in thousands)')
% Add a legend
legend('Measles', 'Mumps', 'Chicken pox')
That should work now

how to position Matlab GUI window at top of screen?

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.

MATLAB Bar Graph Plotting Over Axes

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.

turn on colorbar programmatically in clustergram

I know that one can insert a colorbar by clicking the colorbar icon in the clustergram GUI. Is there a way to do it programmatically?
I tried
cgo = clustergram(data)
colorbar;
This makes a colorbar in a new figure window. How can a colorbar be created with proper positioning in a clustergram figure as if the button was clicked?
There is a function buried away (HeatMap.plot>showColorbar) that neatly positions the colorbar to the left of both the heat map and the dendogram (the lines). Just running colorbar(...) will mess up the relative positioning of the dendogram and the heatmap. So you need to somehow run the callback or carefully duplicate all of the position computations. It's easier to just run the callback. Here's how.
To create the colorbar programmatically for a clustergram, and keep the color bar button in sync, you need to use the button's assigned callback and set the button's state.
Create the clustergram:
load filteredyeastdata
cgo = clustergram(yeastvalues(1:30,:),'Standardize','Row');
Get the handle for color bar button:
cbButton = findall(gcf,'tag','HMInsertColorbar');
Get callback (ClickedCallback) for the button:
ccb = get(cbButton,'ClickedCallback')
ccb =
#insertColorbarCB
[1x1 clustergram]
That gives us a handle to the function assigned by the callback (#insertColorbarCB), and the function's third input argument (the clustergram object). The button's handle and an empty event object are implicitly the first two arguments.
Change the button state to 'on' (clicked down):
set(cbButton,'State','on')
Run the callback to create the colorbar:
ccb{1}(cbButton,[],ccb{2})
Note that the button State must be changed to 'on' first, otherwise the callback won't do anything.
I just managed to solve this problem.
What I did:
I added this function to the clustergram code (I put it at line 1486)
%%%%%%%%%%%%%%
function insertColorbarCBALWAYS(obj)
hFig= gcbf;
obj.Colorbar = true;
end
%%%%%%%%%%%%%%%
and then at line 415 of the clustergram.m file I added this line of code
insertColorbarCBALWAYS(obj);
to call the above function. Save and go: now the colorbar will always be there, once the clustergram is drawn.
Previous method was not working for me so I made this workaround.
One may even save the new clustergram code as clustergramCM such that you can draw cgram in both ways.

removing units from plot

I try to remove the Matlab-given units from this plot but I don't find a way:
figure(1)
hold on
set(gcf,'PaperUnits','centimeters',...
'PaperSize',[15 9],...
'PaperPosition',[0 0 15 9]);
pzmap(LB); sgrid; grid on; axis equal;
title('');
xlabel('\sigma [rad/s]')
ylabel('\omega [rad/s]')
hold off
After that commands the xlabel looks like this: \sigma [rad/s] (seconds^-1). The seconds comes with pzmap. How can I remove them?
I found, some strange behavour:
If generate code by the figure plot manager I get this:
% Create xlabel
xlabel('\sigma [rad/s] (seconds^{-1})','Units','pixels');
Why???
Now I get it - without pzmap/pzplot
pol = pole(sys)
figure(1)
plot(real(pol(:)),imag(pol(:)),'x')
title('');
xlabel('\sigma [rad/s]');
ylabel('\omega [rad/s]');
sgrid
pzmap is a high-level convenience function, but it's not the best choice for this (it's also stored in a folder of obsolete functions in R2013a, so it may get marked for official removal in the future). Instead, let's create an example plot using pzplot directly instead of pzmap. This is still a plot function that does a lot under the hood, but it returns a handle, h, to the plot:
sys = rss(3,2,2);
h = pzplot(sys);
sgrid;
axis equal;
We can via the options of a pzplot with getoptions:
p = getoptions(h)
To set the labels and units as you desire, you might try this, using setoptions:
p.Title.String = '';
p.XLabel.String = '\sigma';
p.YLabel.String = '\omega';
setoptions(h,p);
I believe that the units of 'seconds-1' that the plot displays is equivalent to the 'rad/s' that you want to specify. I know that the two look is very different (I prefer being specific about radians myself), but that's a disadvantage of using such a plot function that tries to do everything for you. If you wanted to remove the default string or add another option, you'd likely have to do some low level hacking. An easier way around, might be to use the "Generate Code..." command ("Generate M-File..." in older versions") under the "File" menu in the figure's toolbar and edit the plot labels there (there's also a programmatic option for this on the File Exchange). Or you could output to postscript and edit that.
Alternatively, you can use pzoptions to create a list of options to pass to pzplot or pzmap (undocumented in the latter case):
p = pzoptions;
p.Title.String = '';
p.XLabel.String = '\sigma';
p.YLabel.String = '\omega';
sys = rss(3,2,2);
pzplot(sys,p);
sgrid;
axis equal;
You'll see that that for some reason the text size is much smaller in this case. pzplot and pzmap must set the font size to 10 themselves. You could easily do this.
Fore more on customizing this and related Control toolbox plots, see this article.
After intense low-level digging, there is actually a pretty simple way to override the default behavior.
p = pzplot(sys);
p.AxesGrid.XUnits = 'rad/s';
p.AxesGrid.YUnits = 'rad/s';
Changes appear to take effect immediately. I have even tried setting the value to nothing, i.e.
p.AxesGrid.XUnits = '';
and it effectively removes the annoying parenthesis with the units. Technically, matlab creates a custom-class element they store under the name AxesGrid in the resppack.mpzplot class instance, with some standard LTI-behavior. You can probably work around some stuff by "injecting" a script with the same name as one of the standard library functions, so that it will be called instead, and change things in there, but this is the closest I have come to removing those annoying units in a few lines.
As a side info, the AxesGrid object is initialized in
...\controllib\graphics\#resppack\#pzplot\initialize.m
should you want to check it out.

Two figures in two different files - how to run first fig from the second one?

I have two figs in two different files.
By clicking a button on first fig I want to show the second one... how to do this? is it possible?
If YES than how to exchange with data between two figures?
There are a number of ways to share data among GUIs. In general, you need to somehow make the graphics handle(s) from one GUI available to the other GUI so it can get/set certain object properties. Here's a very simple example that involves one GUI creating another and passing it an object handle:
function gui_one
hFigure = figure('Pos',[200 200 120 70],... %# Make a new figure
'MenuBar','none');
hEdit = uicontrol('Style','edit',... %# Make an editable text box
'Parent',hFigure,...
'Pos',[10 45 100 15]);
hButton = uicontrol('Style','push',... %# Make a push button
'Parent',hFigure,...
'Pos',[10 10 100 25],...
'String','Open new figure',...
'Callback',#open_gui_two);
%#---Nested functions below---
function open_gui_two(hObject,eventData)
gui_two(hEdit); %# Pass handle of editable text box to gui_two
end
end
%#---Subfunctions below---
function gui_two(hEdit)
displayStr = get(hEdit,'String'); %# Get the editable text from gui_one
set(hEdit,'String',''); %# Clear the editable text from gui_one
hFigure = figure('Pos',[400 200 120 70],... %# Make a new figure
'MenuBar','none');
hText = uicontrol('Style','text',... %# Make a static text box
'Parent',hFigure,...
'Pos',[10 27 100 15],...
'String',displayStr);
end
After saving the above code to an m-file, you can create the first GUI by typing gui_one. You will see a small figure window with an editable text box and a button. If you type something in the text box, then hit the button, a second GUI will appear next to it. This second GUI uses the handle to the editable text box that is passed to it from the first GUI to get the text string, display it, and clear the string from the first GUI.
This is just a simple example. For more information on programming GUIs in MATLAB, take a look at the MathWorks online documentation as well as the links in the answers to this SO question.
