MATLAB: Linking marker face color to colorbar

colorbarcolormapface colormarkerplot

Hi
How do I link the face color of a marker to a colorbar? I have the following code so far:
plot(ones(length(cds_BD),1)*srs(1), v0_BD,'ks'), hold on
plot(ones(length(cds_GD),1)*srs(2), v0_GD,'ks')
plot(ones(length(cds_PRD),1)*srs(3), v0_PRD,'ks')
caxis([40 70]);
colorbar
Where "cds_**" and "srs" are defined arrays. Each entry in the matrix cds_** is linked to a initial velocity and I would like to color the marker's face with that color according to the colorbar.
Please help.
Thanks

Try scatter
clc,clear
cds_BD = [1.1105    1.3124    1.0474    1.0978    1.0852    1.0474    1.0221    1.0347    1.1988];
cds_GD = [0.8256    0.9615    0.9406    0.7524    1.0660    0.7838    0.8256    0.9301    0.7733];
cds_PRD = [0.9761    0.9964    0.9862    1.0472    0.9659    1.0066    0.9252    0.9151    0.9354];
v0_BD = [58.5101   58.2125   58.4750   62.5083   62.4396   62.3959   67.1816   66.3405   66.7731];
v0_GD = [61.1054   61.5469   61.4117   63.8668   64.1549   64.4764   66.8466   67.5859   67.2018];

x0 = cds_BD*0;
h(1) = scatter(x0+1, v0_BD, [], cds_BD);
hold on
h(2) = scatter(x0+2, v0_BD, [], cds_GD);
h(3) = scatter(x0+3, v0_BD, [], cds_PRD);
hold off
set(h,'Marker','s')
set(h,'SizeData',50)
% caxis([40 70]);
colorbar
axis([0 4 55 70])
