How to add legend in a 3D scatter plot?

I have following piece of code. I am using tsne visualization to plot 3D scatter plot. But I am unable to find a way to add legends.

clear all; clc; close all;
load('trLabels.mat')
load('trFeatures.mat')

X = trSets;
L = labels;


rng default % for fair comparison
Y3 = tsne(X,'Algorithm','barneshut','NumPCAComponents',20,'NumDimensions',3);

figure
scatter3(Y3(:,1),Y3(:,2),Y3(:,3),15,L,'filled', '');
colormap( jet(numel(unique(L))) )

 legend(' :) ')

Tried but no luck. It is showing only one entery, whereas I have 11 enteries.

[madhan ravi]

 legend(compose('Entry %d', 1:11))

Having same results.

Can’t help without looking at your file, I would see 11 calls to scatter3() or a loop whereas you have only one ? and you expect 11 entries?

I have added the data files and below is my code.

clear all; clc; close all;
load('trLabels.mat')
load('trFeatures.mat')

X = trSets;
L = labels;

rng default % for fair comparison
Y3 = tsne(X,'Algorithm','barneshut','NumPCAComponents',20,'NumDimensions',3);

figure
scatter3(Y3(:,1),Y3(:,2),Y3(:,3),20,L,'filled', '');
colormap( jet(numel(unique(L))) )

 legend(compose('Entry %d', 1:11))
