How to break ylabels of automatically created scatter plots in several lines?

I post-process data tables, which result from Design of Experiments with m input parameters, n output parameters and > 100 evaluations/lines. I use scatter plots, which are automatically set up in m*n subplots, such that each row of scatter plots shows the effect of input parameters whereas each column of scatter plots shows the impact on the output parameters. The name of the input and output parameters are currenlty displayed only above the first row and left of the first column of scatter plots in order to save as much space between the scatter plots as possible. Above the first row I use plot title and was able to break the very long title (name + unit)

titlename=strcat(A.Name(col+NumIn),' (',A.Unit(col+NumIn),')');
title(titlename,'FontSize',9, 'Interpreter', 'none','Rotation',0);

in several lines according to this code ( https://de.mathworks.com/matlabcentral/answers/224185-how-to-make-long-title-for-a-plot-with-automatic-line-breaks ):

ha=gca; NoCharPerLine= cellfun('length',titlename)-cellfun('length',A.Unit(col+NumIn))-2; % or whatever you want...
if ismatrix(ha(end).Title.String) && size(ha(end).Title.String,2)>NoCharPerLine
  II=strfind((ha(end).Title.String(1:NoCharPerLine)),' '); % find last occurence of a space
  LastSpaceIndex=II(end);
  ha(end).Title.String={ha(end).Title.String(1:LastSpaceIndex-1) ; 
ha(end).Title.String(LastSpaceIndex+1:end)};
end
if iscell(ha(end).Title.String)
    while size(ha(end).Title.String{end},2)>NoCharPerLine
        STR=ha(end).Title.String{end};
        II=strfind(STR,' '); % find last occurence of a space
        LastSpaceIndex=II(end);
        ha(end).Title.String{end}=STR(1:LastSpaceIndex-1);
        ha(end).Title.String{end+1}=STR(LastSpaceIndex+1:end);
    end
end

My question is now how to deal with the automatically concatenated ylables (name+variable+unit) ?

ylabelname=strcat(A.Name(row),' _ ',A.Var(row),'  (',A.Unit(row),')');
ylabel(ylabelname,'FontSize',9 , 'Interpreter', 'none', 'FontWeight','bold');

Like this?

ylabelname=sprintf('%s_{%s} (%s)',A.Name(row),A.Var(row),A.Unit(row))
ylabel(ylabelname,...)

You can also use sprinfc (undocumented) to get a cell array of labels. Something like this

ylabelnames=sprintfc('%s_{%s} (%s)',A.Name,A.Var,A.Unit)

Should give you a list of ylabelnames.

Great, Thx! It eventually works with adapting your code to cell inputs:

ylabelname=sprintf('%s \n %s \n %s',A.Name{row},A.Var{row},A.Unit{row})
ylabel(ylabelname,'FontSize',9 , 'Interpreter', 'none', 'FontWeight','bold');

Ok, I just realized that the same solution of course also applies to titles...
