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 am currently writing up a scientific thesis and am very desparate about creating figures that have the exact dimensions I want them to have. Especially the font sizes do not match.
I already googled alot and there are a bunch of guides and scripts about this topic but nothing really helped - I have not yet figured out (sorry) why my approach does not work:
FS=8; %font size in points (the same as in my document)
width=12; %width of figure in cm
height=4; %height of figure in cm
scatter(1:20,rand(20,1));
xlabel('X','fontsize',FS),ylabel('Y','fontsize',FS),title('X vs. Y','fontsize',FS)
%now I scale the figure and place it in the bottom left corner. The white margins around it are cropped automatically
set(gca,'units','centimeters','outerposition',[0 0 width height])
%export as .eps
print(gcf,'-depsc','test')
When I load test.eps into Inkscape, the figure is 10.16 x 3.529 cm large and the font sizes (of title and axis labels) are 10.
How do I get a figure with the exact scaling, especially regarding the font size?
I did the following:
FS=8; %font size in points (the same as in my document)
width=12; %width of figure in cm
height=4; %height of figure in cm
scatter(1:20,rand(20,1));
set(gca, 'fontsize', FS);
xlabel('X','fontsize',FS),ylabel('Y','fontsize',FS),title('X vs. Y','fontsize',FS)
set(gcf,'units','centimeters','position',[0 0 width height])
export_fig(gcf, 'test.pdf', '-transparent', '-nocrop')
The output figure is 12cm x 4cm. The font size still claims to be 10 in Inkscape, however, but it looks the same size as that in the figure. Export_fig can be downloaded from the MATLAB file exchange.
Here is how I solve it as of now - it is not exactly elegant but it works...
I plot my figure and arrange and scale it in the figure window the way I want it to be scaled:
set(gcf,'units','centimeters','position',[0 0 width height])
Due to the white margins around the axes, I increase the width/height by approximate (trial and error...) values that the margins use up. I then export it:
export_fig(gcf,'test','-eps','-transparent')
And load it into Inkscape. Now I set the document properties so that the document has the exact size I want my figure to have - the figure is partly out of this frame because I increased the width/height earlier.
Then I arrange the axes to have as much white space between them as I want them to have; hopefully, everything is inside the document borders after that.
Probably the drawing is smaller than the document borders now - to ensure that it will not get expanded, messing up the scaling, when I put it in my actual document (my thesis, not the Inkscape document...), I simply create a white background that matches the document borders. Aaand done.
Except for the fontsize and fontname properties in Matlab - I have not figured out why they are not properly exported...but this is not hard to manually fix in Inkscape.
Thanks for your help, everyone.
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.
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 want to display overlapping boxplots using Sigmaplot 12. When I choose the scale for the x-axis as linear then the boxes do indeed overlap but are much too thin. See figure below. Of course they should be much wider.
When I choose the scale of the x-axis to be "category", then the boxes have the right width, but are arranged along each single x-value.
I want the position as in figure 1 and the width as in figure 2. I tried to resize the box in figure 1 but when I choose 100% in "bar width" than it still looks like Figure 1.
many thanks!
okay, I found the answer myself. In Sigmaplot, there is often the need to prepare "style"-columns, for example if you want to color your barcharts, you need a column that holds the specific color names.
For my boxplot example I needed a column that has the values for "width". These had to be quite large (2000) in order to have an effect. Why ? I have no idea. First I thought it would be because of the latitude values and that the program interprets the point as "1.000"s, but when I changed to values without decimals, it didn´t get better.
Well, here is the result in color.
Have fun !
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.
