Vertical blank space in tiledlayout compact

Dear all

I am plotting the following:

set(u1,'Units','Inches');
posu1=get(u1,'Position');
set(u1,'PaperPositionMode','Auto','PaperUnits','Inches','PaperSize',[posu1(3),posu1(4)]);

and the plot looks like:

As you can see there is some vertical unnecessary space between the two horizontal stacks of plots. I would like to reduce it to be able to put the general title "Bilayer..." far enough from the top plots.

Any ideas?

Hi Richard,

A possible way to reduce the extra spacing between tiles of the tiled-layout is by using 'TileSpacing' option and setting its value to 'none'.

Please refer the following documentation link for more details:

Trying setting TileSpacing to compact or tight.

t=tiledlayout(2,2,'Padding','compact','TileSpacing','compact');

Or:

t=tiledlayout(2,2,'Padding','compact','TileSpacing','tight');

Also, since you need room for an overall title, you might want to set Padding to loose instead of compact:

t=tiledlayout(2,2,'Padding','loose','TileSpacing','compact');

Hello,

At line 3 (definition of title), change the brackets around the title by curly braces:

{'Bilayer. Monte Carlo, $15$ million steps. $T=2$ K, $\mathbf{H}=0$';'';''}

That's how you create subtitles in the title function, here you have 2 lines of subtitles and you can add as much as you want.

If the main goal is to insert space between the global title and the first row of axes, you can add empty rows of text under the title. It looks like you were heading in that direction based on the rows of empty characters at the end of your title string. But those empty characters are trimmed.

title(t,['Bilayer. Monte Carlo, $15$ million steps. $T=2$ K, $\mathbf{H}=0$';'';''],'FontSize',18,'interpreter','latex');

Instead, use newline to insert newline characters to the end of the string.

title(t,['Bilayer. Monte Carlo, $15$ million steps. $T=2$ K, $\mathbf{H}=0$',newline(),newline()],'FontSize',18,'interpreter','latex');
