colorbar for line plot number

I want to use a colorbar as indicator for the number of a series of line plots.

Actual limits of the colorbar: 0 to 1

Intended limits for the colorbar: Limits from 1 to 10

Example code:

Nc = 10;
x=[0 2];

figure();
colororder(parula(Nc));
for i=1:Nc
    if i==1
        hold on;
    end
    plot(x, i*x);
end
colorbar;

The colorbar apparently does not want to do this by itself, since it appears to scale to the ‘z’ values in a 3D plot (or equivalent, such as contour).

The only way to have it do what you want in this instance is to tell it —

Nc = 10;
x=[0 2];

figure();
colororder(parula(Nc));
i=1:Nc;
plot(x, i(:)*x);
hcb = colorbar;
tix = hcb.Ticks;
hcb.TickLabels = compose('%2.0f',tix*Nc);
