how to set the range in the colorbar manually?

Question

I have a wide range of values and while plotting as a scatter(x,y,z), the colorbar showing the z axis shows a wide range of values, now I am not interested in the lower rang

Answer 1

How about this?

% don’t know why, but apparently your x and y are one value too long?
x = x(1:end-1); y = y(1:end-1); 

% only plot values of 14 or higher
scatter(x(gnd>=14), y(gnd>=14), 5, gnd(gnd>=14);
