Scatter: Vary the color along the axis x

Hello,

I want to plot using scatter(). I want to color the dots in a way that all the dots with equal x to be the same color.

Here is the code I tried:

clc; clear all;

x = [1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,5,5,5,5];
y = [1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4]; 
sz = 100;
c = linspace(1,6,length(x)); 
scatter(x,y,sz,c,'filled','o');

xlim([0 6]);
ylim([0 5]);

Here is what it produces instead the example given in https://www.mathworks.com/help/matlab/ref/scatter.html

The colors vertically are not the same (yes, they are almost similar, but, e.g. on the last column you can see that the yellow dot on the top is different from the orange one on the bottom)

Use the ‘x’ vector to determine the dot colours:

scatter(x,y,sz,x,'filled','o');

They all appear to be completely uniform.
