Hi, can someone help me to add a legend to a panel created by labelvolshow? I managed to add a title but I really don't know how to put a legend (or at least a colorbar, even if I know it wouldn't be the same thing). Any kind of "legend" is accept: I mean, not just the output of the classic legend function; also some strings, written in the color of the data, can be fine for example..any way to categorize the output is welcome, the important thing is that I'd like it to be automatically generated by the code - no interactions with the panel required.
This is how I add a title:
view_panel = uipanel(figure,'Title',"Titolo");
view_panel.FontSize=14;
view_panel.TitlePosition='centertop';
labelvolshow(volume_labeled,'Parent',view_panel);
Thanks in advance

Ran in:
Maybe something like this can be a start:
volume_labeled = randi(10,[5 5 5]);
view_panel = uipanel(figure,'Title',"Titolo");
view_panel.FontSize=14;
view_panel.TitlePosition='centertop';
h = labelvolshow(volume_labeled,'Parent',view_panel);
NC = size(h.LabelColor,1);
ax = axes( ...
'Parent',view_panel, ...
'Units','normalized', ...
'Position',[0.93 0 0.07 1], ...
'Visible','off', ...
'YLim',[0 10], ...
'CLim',[0 10], ...
'Colormap',h.LabelColor);
p = patch( ...
'Parent',ax, ...
'XData',repmat([0; 1; 1; 0],1,NC), ...
'YData',[0;0;1;1]+(0:NC-1), ...
'FaceColor','flat', ...
'FaceVertexCData',ax.Colormap);
t = text(ax,0.5*ones(1,NC),(1:NC)-0.5,sprintfc('%d',1:NC), ...
'HorizontalAlignment','center');
t(1).Color = [1 1 1];

unfortunately I do not seem to replicate this with a minimal test. Would it be possible for you to attach data and enough code to reproduce the problem?

Attaching the whole process would be too cumbersome. Anyway, if you want to try, you can create sample E data like this:
E=ones(5,5,3);
E(1,:,:)=100000; % defining bg (far higher)
E(5,:,:)=100000;
E(:,1,:)=100000;
E(:,5,:)=100000;
E(2:4,2:4,1)=randi(100,3); % defining much lower values
E(2:4,2:4,2)=randi(100,3);
E(2:4,2:4,3)=randi(100,3);
and then use the visualization code I've attached before
tuttiE=E(:);
n_cluster=6; % and so on...
I've tried with this and I get the same problem so you can try too, if u want. Thanks again
