Boxplot multiline labels with latex interpreter

20 views (last 30 days)
I am trying to plot a boxplot for data with two different lines for each label that are strings constructed from values of a matrix.
tol_r_f=[0 .2;0 .04;0 .03;.1 1];
tol_v_f=[.3 1;.09 .2;0 .07;1 10];
range={{[num2str(tol_r_f(1,1)) '$\leq ||\boldmath{r}_f|| \leq$' num2str(tol_r_f(1,2))];...
[num2str(tol_v_f(1,1)) '$\leq ||\boldmath{v}_f|| \leq$' num2str(tol_v_f(1,2))]},...
{[num2str(tol_r_f(2,1)) '$\leq ||\boldmath{r}_f|| \leq$' num2str(tol_r_f(2,2))];...

There must be the same number of labels as groups or as the number of elements in X.

I couldn't get it to work either, but here's a workaround where you create text objects instead of setting the xticklabels (shown for the first figure only):
tol_r_f=[0 .2;0 .04;0 .03;.1 1];
tol_v_f=[.3 1;.09 .2;0 .07;1 10];
range = sprintfc([ ...
'%g$\\leq ||\\boldmath{r}_f|| \\leq$%g\n' ...
'%g$\\leq ||\\boldmath{v}_f|| \\leq$%g'], ...
[tol_r_f, tol_v_f])
range = 4×1 cell array
{'0$\leq ||\boldmath{r}_f|| \leq$0.2↵0.3$\leq ||\boldmath{v}_f|| \leq$1' } {'0$\leq ||\boldmath{r}_f|| \leq$0.04↵0.09$\leq ||\boldmath{v}_f|| \leq$0.2'} {'0$\leq ||\boldmath{r}_f|| \leq$0.03↵0$\leq ||\boldmath{v}_f|| \leq$0.07' } {'0.1$\leq ||\boldmath{r}_f|| \leq$1↵1$\leq ||\boldmath{v}_f|| \leq$10' }
x_t1=rand(1,50);
g_t1=[zeros(1,10) ones(1,20) 2*ones(1,10) 3*ones(1,10)];
x_t2=rand(1,50);
g_t2=[zeros(1,10) ones(1,20) 2*ones(1,10) 3*ones(1,10)];
x_tf=rand(1,50);
g_tf=[zeros(1,10) ones(1,20) 2*ones(1,10) 3*ones(1,10)];
figure(1)
boxplot(x_t1,g_t1)%,'labels',range)
yl = ylim();
yt = yl(1)-0.02*(yl(2)-yl(1));
xt = xticks();
nt = numel(xt);
xticklabels(repmat({''},1,nt));
text(xt,yt*ones(1,nt),range, ...
'Interpreter','latex', ...
'HorizontalAlignment','center', ...
'VerticalAlignment','top')
xlabel(sprintf('\n\n\nCluster Ranges'),'Interpreter','Latex')
ylabel('$\% t_1$','Interpreter','Latex')
