Scatter Plot and Contours

I would like to include contours in my scatter plot to differentiate between sets of data (2 in this case).

Does anyone know what I would have to adjust in my code to get a similar result as in the picture attached?

Thanks in advance

figure
Size = 50; 
hold on
HS = scatter(F(1:10,1),F(1:10,2),'+','SizeData',Size,'MarkerEdgeColor',[0 0 1],'MarkerFaceColor',[0 0 1]);
FO = scatter(F(21:30,1),F(21:30,2),'+','SizeData',Size,'MarkerEdgeColor',[1 0.8 0.2],'MarkerFaceColor',[1 0.8 0.2]);
FT = scatter(F(31:40,1),F(31:40,2),'+','SizeData',Size,'MarkerEdgeColor',[1 0.8 0.2],'MarkerFaceColor',[1 0.8 0.2]);
FK = scatter(F(41:50,1),F(41:50,2),'+','SizeData',Size,'MarkerEdgeColor',[1 0.8 0.2],'MarkerFaceColor',[1 0.8 0.2]);

Alternatively, it would also be useful to be able to connect data points with an arrow like in this picture:

Any help is appreciated!

It would be best to classify them first and let the classification function determine the contours. See the documentation for the classify (link) function for that and plotting the results.
