Grouped scatter plot withe symbols and color defined colors and shapes (for loop?)

Hi,

I want to create a grouped scatter plot, which is grouped by color, and further subgrouped by symbols, i.e. every color-group is subdived by different symboles. In the end I want one scatter plot with e.g. blue circles & plus & crosses, red cirles & plus & crosses, etc...

X has the data for the x-axis Y has the data for the y-axis C defines the color of each XY pair (e.g. from 1 to 4, where 1=blue, 2=red, 3=green, 4=black) S defines the shape of each XY pair (e.g. from 1 to 3, where 1=circle, 2=plus, 3=cross)

So far, I managed to group the scatterplat using gscatter(x,y,c), which works. I was given the hint to use a for-loop to change the symbol shape according to S, but have no idea how to do that.

Any suggestions?

Thank you!

I don’t know if this is what you are asking for, but it may be part of the solution:

Mrkr = '+o*.xsd^v><ph';
C = colormap(jet(length(Mrkr)));

for k1 = 1:13
    XData(:,k1) = 2*k1+k1*randn(10,1);
end
YData = randi(25,10,13);

figure(1)
hold on
for k1 = 1:13
    scatter(XData(:,k1), YData(:,k1), 15, 'Marker',Mrkr(k1), 'MarkerFaceColor', C(k1,:))
end
hold off
