Set specific Marker Edge and Face Colour for gscatter group of points

I want to colour edge and face of marker point on the base of values in g.

h=gscatter(x,y,g,clr,sym,siz)

But there are 2 problems:

• I do not know a-priori how many groups of points (elements in g with different values) I have.
• I want each specific group has a specific couple of marker face colour and marker edge colour that I define. For example if g(10)=3.5 i need to set marker face colour [1 1 1] and marker edge colour [0 0.6 0.8].

If I had the possibility to relate each h(i) Line Objects to the corresponding g(j) value I could set exactly the colors with commands:

h(i).MarkerEdgeColor=[ colour related to g(j) ];

h(i).MarkerFaceColor=[ colour related to g(j) ];

Example in the attached file

Wondeful I resolved with this loop on I values (values in accordance with which I define RGB triplets), but not without SS benediction, because hgscat create by default gscatter objects sorted in ascending order regardless of the order of M_Pts(:,i) group markers (numbers).

fMarkFaceCol(I) and fMarkEdgeCol(I) give me the triplet RGB according to the I values

hgscat=gscatter(M_Pts(:,2),M_Pts(:,1),M_Pts(:,i),[],'o',[],'on');

k=1;

for I=1:0.5:11

if k<=length(hgscat)

if ismember(I,M_Pts(:,i))

hgscat(k).MarkerFaceColor=fMarkFaceCol(I);

hgscat(k).MarkerEdgeColor=fMarkEdgeCol(I);

k=k+1;

end

end

end
