evolution2012.fig

I have a figure with 2x2 subplots. I want to make the subplots side by side so that there is no spacing between the subplots.

I used the "subplottight" function written by Brian D'Alessandro here: https://www.briandalessandro.com/blog/how-to-make-a-borderless-subplot-of-images-in-matlab/

%subplottight function by Brian D'Alessandro:
function h = subplottight(n,m,i)
    [c,r] = ind2sub([m n], i);
    ax = subplot('Position', [(c-1)/m, 1-(r)/n, 1/m, 1/n])
    if(nargout > 0)
      h = ax;
    end
end

I works like a charm to remove the vertical spacing between my subplots but I am still left with spacing vertically (see figure below).

How can I modify the "subplotitght" function to also remove the space horizontally?

Thank you

Consider using tiledlayout instead of subplot. You can then use the TileSpacing input to adjust the spacing.

t = tiledlayout(2,2,'TileSpacing','none');

I am not aware of creating any white space in my plot. What command would generate a white space between plots?

I have attached my data in "data.mat"

Here is my code for the figure:

Can you share your data? Save your variables to a mat file and attach it to your post using the paperclip icon.

Another simple test to run is creating a figure of just one of your plots with the axis on to see what is happening.

%plot the land (grey) and and oceans (white)
p=pcolor(Land);
p.Annotation.LegendInformation.IconDisplayStyle = 'off';
colormap(cmap);
hold on;
shading flat;
axis ij;
axis equal;
%plot alphaShape for LITS
h = plot(LITS31,'FaceColor',cbrewer3(5,:),'EdgeColor','none');
%contour for starting position
[M1,c1] = contour(xx,yy,EASE31,1,'LineWidth',4.5,'Color', cbrewer3(9,:));
%contour for ending position
[M2,c2] = contour(xx,yy,EASE32,1,'LineWidth',4,'Color',cbrewer3(11,:));
mask = contour(xx,yy,Mask,1,'LineWidth',1,'Color','black');
h4 = plot(Xstorm,Ystorm, '--o','LineWidth',2,'MarkerSize',7,'Color','red','MarkerFaceColor','red','MarkerEdgeColor','red');
text(Xstorm(1),Ystorm(1),'  02 Aug','FontSize',14);

I'm having a similar problem where after i change my DataAspectRatio for my two subplots, it creates a huge space in between them, even though my TileSpacing = 'none'.

Cris LaPierre 2022-7-26

This is likely caused by a similar issue.

Stretch-to-Fill

When the “stretch-to-fill” behavior is enabled, MATLAB stretches the axes to fill the available space. The axes might not exactly match the data aspect ratio, plot box aspect ratio, and camera-view angle values stored in its DataAspectRatio, PlotBoxAspectRatio, and CameraViewAngle properties.

If you specify the data aspect ratio, plot box aspect ratio, or camera-view angle, then the “stretch-to-fill” behavior is disabled. When the behavior is disabled, MATLAB makes the axes as large as possible within the available space and strictly adheres to the property values. There is no distortion. For more information, see Control Axes Layout.

data.mat

It looks like plotting the alphaShapes (e.g., LITS31) sets the DataAspectRatioMode of the axes to 'manual' so that although the Positions of the axes span the space allotted by the tiledlayout with TileSpacing 'none', the actual space used is less than that in order to maintain the 1:1 X:Y aspect ratio.

One way to get around that is to set each axes' DataAspectRatioMode back to 'auto' after the alphaShape is plotted. And, since now the text objects (e.g., W31-32) can overlap with other axes, it is also necessary to change the child order of the axes at the end.

I'm not sure that allowing an aspect ratio that's not 1:1 is the best thing to do though, since it means your maps can be distorted (i.e., different scales in Lat and Long direction).

Ok, interesting. Thank you for your time.

However, the figure does seem to be distorsted compare to my initial figure.

I guess I will just keep the "adjust figure window" solution.
