Different labels are represented by different colors

Hello,

I have a scatter plot like figure1.

But I would like to show that same name with same color, different name with deferent color.

And also shown on legend.

As shown in Figure2, First row is name , second and third row are data.

Attachment is Test.mat , included matrix value .

Thanks.

Figure1:

Fifure2:

load test.mat
scatter(matrix(:,2),matrix(:,3),'ko','MarkerFaceColor','k')

[Walter Roberson]

gscatter(matrix(:,2), matrix(:,3), matrix(:,1))

Notice the gscatter() instead of scatter()
