I'm trying to adjust two subfigures into one row. This is my code:
\begin{figure}[ht]
\centering
\caption{Migration rates and nightlights in Albania in 1992-1995}
\begin{subfigure}[a]{0.3\textwidth}
\caption{Emigration rate before 1995 at the municipality level}
\label{fig: migration_rate}
\includegraphics[width=\linewidth, trim = 5cm 0cm 5cm 0cm, clip]{Figures/migration_rate.pdf}
\end{subfigure}
\begin{subfigure}[b]{0.3\textwidth}
\caption{Night luminosity in 1992}
\label{fig: nighlights}
\includegraphics[width=\linewidth, trim = 5cm 0cm 5cm 0cm, clip]{Figures/nightlight.pdf}
\end{subfigure}
\caption*{\footnotesize{\textbf{Notes}:}}.
\end{figure}
enter image description here
Even if I shrink the subfigure to tiny size (for example {0.01\textwidth}), the two always appear in one column. I have deep blank space on the left and right of both figures that I have tried to trim. Including or excluding "trim" does not change much.
How do I get the two into one row?
Thank you!

How do I place a textclip, right below the other? I require to place an image at the left of the video and two lines of text to the right of image, that are placed one below the other.
Something like this:
I tried to use set_position, but doesn't scale well for different videos (of different resolutions). By adjusting the arguments of set_position, I am able to place the textclips one below the other without gap in one resolution, but when I go to a higher resolution video, it shows a gap (I understand why the gap comes, but not sure how to prevent it)
txt_clip1 = TextClip("This is line 1 of text", fontsize = 12, color = 'white', bg_color='black')
txt_clip1 = txt_clip1.set_duration(7).set_start(0).set_end(7)
txt_clip1 = txt_clip1.set_position((0.1,0.90), relative=True).set_opacity(0.6)
txt_clip2 = TextClip("This is line 2 of the text, smaller font", fontsize = 8, color = 'white', bg_color='black')
txt_clip2 = txt_clip2.set_duration(7).set_start(0).set_end(7)
txt_clip2 = txt_clip2.set_position((0.1,0.93), relative=True).set_opacity(0.6)
I tried to insert a new line character in the text, but that doesn't suit me because the second line of text has different font properties.
Hopefully this will help you
txt_clip1 = TextClip(
"Cool effect 2nd line", color="black", bg_color="red", font="Amiri-Bold", kerning=5, fontsize=20
)
cvc = CompositeVideoClip([txt_clip1.set_position("East")], size=screensize)
txt_clip1 = txt_clip1.set_position((5,35))
.set_position mother take to arguments 1st is the position from the left screen and second is the position from the top
so your code is like something
txt_clip1 = txt_clip1.set_position((5,500))
txt_clip2 = txt_clip2.set_position((5,535))
It will place the text in the position you want.
Hopefully, this will help.
Happy coding
I have a histology image like this:
From the image, we can observe there are two kinds of different cells.
and
Is there any way that I can separate these two types of cells into two groups?
How about using your raw image and previous code to achieve this?
% % % your old code
I=imread(file);
t1=graythresh(I);
k1=im2bw(I,t1);
k1=~k1;
se = strel('disk',1);
k0=imfill(~k1,'holes');
cc = conncomp(k0);
k0(cc.PixelIdxList{1})=0;
k1=imfill(k1,'holes');
mask=k0 | k1;
%%%%%%%%%%%%%%%%%%
This will give you:
I=rgb2hsv(I);
I=double(I);
I1=I(:,:,1); % again, the channel that can maximizing the margin between donut and full circle
Imask=(I1-0.2).*(I1-0.9)<0;
k2=mask-Imask;
k2=bwareaopen(k2,100);
This will give you:
k2=mask-Imask;
I2=zeros(size(I1,1),size(I1,2),3);
I2(:,:,1)=(k2==1)*255;
I2(:,:,3)=((I1-0.2).*(I1-0.9)<0)*255;
imshow(I2)
will finally give you (the two types are stored in two channels in the rgb image):
I would use regionprops
props=regionprops(YourBinaryImage, 'Solidity');
The objects with a high solidity will be the disks, those with a lower solidity will be the circles.
(Edit) More formally:
I=imread('yourimage.jpg');
Bw=~im2bw(I, 0.5);
BWnobord = imclearborder(Bw, 4); % clears the partial objects
Props=regionprops(BWnobord, 'All');
solidity=cell2mat({Props.Solidity});
Images={Props.Image};
Access the elements of Images where the value in solidity is higher than 0.9 and you get your disks. The circles are the other ones.
Hope it helps
I'm trying to use the answers I found in these questions:
How to save a plot into a PDF file without a large margin around
Get rid of the white space around matlab figure's pdf output
External source
to print a matlab plot to pdf without having the white margins included.
However using this code:

% SAVETIGHTFIGURE(H,OUTFILENAME) Saves figure H in file OUTFILENAME without
% the white space around it.

% get the current axes
ax = get(h, 'CurrentAxes');
% make it tight
ti = get(ax,'TightInset');
set(ax,'Position',[ti(1) ti(2) 1-ti(3)-ti(1) 1-ti(4)-ti(2)]);
% adjust the papersize
set(ax,'units','centimeters');
pos = get(ax,'Position');
ti = get(ax,'TightInset');
set(h, 'PaperUnits','centimeters');
set(h, 'PaperSize', [pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);
set(h, 'PaperPositionMode', 'manual');
set(h, 'PaperPosition',[0 0 pos(3)+ti(1)+ti(3) pos(4)+ti(2)+ti(4)]);
% save it
%saveas(h,outfilename);
if( orientation == 1)
orient portrait
else
orient landscape
end
print( '-dpdf', outfilename );
end
Results in this output:
As you can see the 'PaperSize' seems to be set not properly. Any idea of possible fixes?
NOTE
If I change the orientation between landscape and portrait the result is the same, simply the image is chopped in a different way.
However if I save the image with the saveas(h,outfilename); instruction the correct output is produced.
Why is this? And what is the difference between the two saving instructions?
Alltogether the answers you mentioned offer a lot of approaches, but most of them didn't worked for me neither. Most of them screw up your papersize when you want to get the tight inset, the only which worked for me was:
set(axes_handle,'LooseInset',get(axes_handle,'TightInset'));
I finally wrote a function, where I specify the exact height and width of the output figure on paper, and the margin I want (or just set it to zero). Be aware that you also need to pass the axis handle. Maybe this functions works for you also.
function saveFigure( fig_handle, axes_handle, name , height , width , margin)
set(axes_handle,'LooseInset',get(axes_handle,'TightInset'));
set(fig_handle, 'Units','centimeters','PaperUnits','centimeters')
% the last two parameters of 'Position' define the figure size
set(fig_handle,'Position',[-margin -margin width height],...
'PaperPosition',[0 0 width+margin height+margin],...
'PaperSize',[width+margin height+margin],...
'PaperPositionMode','auto',...
'InvertHardcopy', 'on',...
'Renderer','painters'... %recommended if there are no alphamaps
);
saveas(fig_handle,name,'pdf')
end
Edit: if you use painters as renderer saveas and print should produce similar results. For jpegs print is preferable as you can specify the resolution.
I made a simulation of 10000 times and want to view part of simulation between 5000-5200. I am able to view it with the code below, but the x-axis says 0-250. I want the x-axis to display the exact figure of 5000-5200. Also there seems to be a small gap at the end of the figure as the axis runs up to 250 for some reason. I just want to view the figure in for this set time with the x-axis showing the exact labels and without the gap at the end.
Thanks

Plot expects two inputs, the first depicting the horizontal axis and the second depicting the vertical axis. When you do not supply two inputs, then it computes the length of the single input (in this case that length is 5200-5000 = 200), and it just uses 1 through that length (1:200 in this case) as if it is the values for the horizontal axis variable.
I think you want to issue the command:
plot(5000:5200, X(5000:5200,1), 'r')
Often Matlab will adjust plot axes for better default views, so it's probably showing the axis out to the index 250 just by virtue of some default plotting convention. You can similarly use set(gca, 'xlim', [5000 5200]) if you wish.
I'm writing a table of contents to a standard 8.5in x 11in page. Orientation (landscape versus portrait) is a variable. I can write my TOC to an inner region when x-inch margins are applied to the page (where x is variable).
The raw data is a table with two columns: Topic and Page (i.e. { "Animals" , 1 } , { "Big Plants" , 2 } , { "Small Plants" , 2 } ). This is not a nested TOC - there are no "subtopics". All topics are at the same level of importance and font size is fixed for all text.
I want to allow for 1 or more columns of TOC per page and I'm allowing multiple pages of TOC if needed. The layout is completely dependent on text in the Topic column. If the topics are short, you can imagine putting 2 columns in portrait orientation, or 3 columns in landscape orentation. If there are long topic names, then maybe only 1 column will fit (if very long, then its ok to use multiple lines for a topic). If there are many topics, then I might spill over to multiple pages. The goal is to put as much TOC info as possible on each page.
I realize this is a hard problem. There's a number of details that I haven't explored (i.e. do all pages have to have the same number of columns?). I'm just looking for a start...something simple enough to implement in an hour or two that does the job. Anything semi-intelligent is better than forcing a 1-column TOC with character counts to determine how many rows to place on a page.
First you need a few variables:
Line_hight (inches per TOC line)
Max_TOC_width (inches of the longest TOC name)
Max_pagenum_width (inches width of the largest page number when printed)
Left, Right, Top, Bottom _border (inches of the border around the page)
Then it's pretty easy to calculated.
Lines_Per_Page = Floor( (Page_Height - Top_Border - Bottom_Border) / Line_Height )
Columns_Per_Page = Floor( (Page_Width - Left_Border - Right_Border) / (Max_TOC_Width + Max_PageNum_Width) )
Total_TOC_Per_Page = Lines_Per_Page * Columns_Per_Page
FYI: Floor( ) means round down to the nearest integer. Floor(5.9) = 5, Floor(0.1) = 0
Assuming you want all columns to be the same width:
Do one pass through the table finding the (printed) width of the longest TOC entry.
Divide the page width minus margins and take the floor to figure out how many columns you can fit.
Divide the page height minus margins by the height of a line and take the floor to figure out how many lines per column.
Repeat steps 2 and 3 in the other page orientation (e.g., landscape).
Choose the one that gives the most slots (rows times columns).
The math is slightly more complicated, since you need to account for a "gutter" between the columns. This is easily accomplished by padding your widest value.
