How can i plot coloured dots ?

A = [9,-5,838;9,-6,1087;10,-4,1669;9,4,747;9,5,925;9,6,973;10,1,1150;9,1,1236;9,3,563;10,-2,1085;10,-1,1150;40,4,787;10,6,750;10,-6,1070];
img = imread('Auto_grid.png');
figure;
imagesc(img);
figure;
scatter(M(:,1), M(:,2), 50, M(:,3), 'Filled')
colormap(jet(size(M,1)))
grid on

the Position in X and Y is saved in the array

the first row are the x values

the second row are the y values

the third row are my calculated values (HIC)

the colour depends on the third row

so if the HIC value :

in the end it should look like the png file in the attachment.

g={hic};
gscatter(x,y,g,'rygb','*',8,'Age','Weight');
