I have a scatterplot where the points are colored by group number. How do I add a legend with the group color attached?

I have a scatter plot with each point colored by it's cluster number (ranging from 1 to 5) and I'm trying to add a legend that will indicate which color belongs to which group.

scatter(Data.X, Data.Y, Data.ClusterNumber); legend(strcat('Group: ', num2str(transpose(1:5))))

The above gets me the scatter plot and legend, but there is only a single dot for all 5 clusters.

If you have the Statistics and Machine Learning Toolbox, it is probably easier to use the gscatter (link) function.
