Spaceplots

Customize spaces between subplots in a figure

| Watch this File

File Information
Description

Matlab's standard "subplot" function leaves large blank spaces around the plot boxes and gives the user no control over them. Spaceplots is an elementary function to get control over these spaces. I wanted to save space by making tight subplots, so I wrote this function. Thought it will be useful to others too.

>> Create your figure first, and then use spaceplots. It is a very non-intrusive function.

>> Works well with all subplot arrangements (including a mixture of large and small plots)

>> Preserves the axes line-up in the grid by manipulating insets properly

>> Does not work with multiple plots created in a figure by any function other than the Matlab default "subplot" function.

I hope the function is simple enough for anyone to rectify errors or make changes that suit them.

Is there a way to connect different subplots, as in subplot(4,2,[1,3,5])?

Hello! I would like to report a bug. In some case of figure deleting one get the error in function "removeAxesFromGrid(p,ax)" at command "rmappdata(p,'SubplotListeners')" -- this field does not exist. So, I propose to add a verification via "isappdata".

With v3.0, the earlier errors with legend and colorbars will now disappear!

For those who get the error
"Attempted to access GridLeft...index must be a positive integer or logical", you need to call spaceplots BEFORE changing axis ticks, or adding colorbar, etc... For example for the colorbar, try

a1=subplot(2,1,1);scatter(rand(10,1),rand(10,1),5,rand(10,1))
a2=subplot(2,1,2); scatter(rand(10,1),rand(10,1),5,rand(10,1))
spaceplots
axes(a1); colorbar
axes(a2); colorbar

Outstanding!

When I use image or imagesc with a colour bar I get the following error:

Attempted to access GridLeft(0,4); index must be a positive integer or logical.

Error in spaceplots (line 228)
axLeft = GridLeft(r0,c0) + InsetLeft(r0,c0);

Try this code as an example:

figure;
for i = 1:8
subplot(2, 4, i);
imagesc(rand(100, 10));
colorbar;
end;
spaceplots([.01 .01 .01 .01], [.02 .02]);

With the axis ticks disables (set(gca,'xtick',[],'ytick',[])) I receive an error in spaceplots 228: "Attempted to access GridLeft(0,12); index must be a positive integer or logical.". Does anyone know how to fix it? I want to have all the plots directly adjacent without any visible axis or ticks in between.

Thanks a lot man :-)
I really need this function, the sapce between subplots was only wasted space!!!

02 Aug 2012 Christine A.

Excellent! This is a very useful function. Note that, to save the figure exactly as it appears on the screen, you need this extra line:

set(gcf,'PaperPositionMode','auto');

Thanks a lot Aditya for taking the vodoo out of subplots! ;)

Hi Ralph,

Thanks for your feedback. I've updated the file with your suggestion and a couple of minor fixes.

I'm curious though, I've never had the problem you mentioned during my use. Comparing floats is bound to crash when you are comparing values of two variables that have been computed. But in this case essentially it is the exact same value assigned to the variables being compared, in which case there should be no problem.

Great function. I like the idea of simplicity and non-obtrusiveness. On first use, it failed on my system (therefor four stars instead of five). This was because of this condition evaluating to false where it should have been true:

if axPos(4) == defAx(4)

Comparing floats can be a dangerous thing. For improved robustness you might want to consider rewriting this into

if abs(axPos(4)-defAx(4)) < eps

The same holds for the similar check a couple of lines below.

1. Fixed the issues occurring in successive uses of the function on the same figure.

v3.0: Uses undocumented Matlab property 'LooseInset' which makes the function much simpler and cleaner.

Included subplot.m for v3
