I have been facing this problem that when I do colormap, there are always lines between my data points. I don't know how to efficiently let them gone. I have tried "shading interp' and 'linestyle','none', but none of them work. I have my figure looks like down below, and my code is like:
custom_colormap = [
0 0 1 ; ... %// blue
0 1 0 ; ... %// green
1 1 0 ; ... %// yellow
1 .5 0 ; ... %// orange
1 0 0 ; ... %// red
] ;
figure(1);
box on;
xx=[Sc_frac Sc_frac];
yy=[B_frac B_frac];
zz=zeros(size(xx));
cc=[correctM correctM];
hs=surf(xx,yy,zz,cc,'EdgeColor','interp','FaceColor','none','Marker','.');
hold on;
xx=[Sc_frac Sc_frac];
yy=[B_frac B_frac];
zz=zeros(size(xx));
cc=[correctM correctM];
hs=surf(xx,yy,zz,cc,'EdgeColor','interp','FaceColor','none','Marker','.','MarkerSize',30,'LineStyle','none');

Your variable custom_colormap is not used after it is defined, and your code does not appear to create a colorbar.

I see two possibilities:
1) that the lines you refer to are the black lines between elements of the colorbar on the right hand side, which the code you presented does not create; or
2) that the lines you refer to are the connecting lines between the points. If you do not want them then you should probably be using scatter() instead of surf(). If there is some good reason to use surf then your EdgeColor should be 'none' instead of 'interp'

You probably do not need the zz as you appear to be doing a 2D scatter. It wouldn't really hurt to use the zz with a scatter3(): with constant z, the difference is that the scatter3 version could be rotated off-plane which could matter if you were plotting multiple objects in the same axes.
