Hello, experts.
I want to draw a color bar with discontinuous and regular intervals like the first picture above.
However, it would be best to draw a continuous color bar like the second picture. Is there a solution?

You can call the colorbar function with the desired tick values
Z = peaks;
contourf(Z)
colorbar('ticks',[-6:0.5:8])

you can use the 'colorbar' function. This allows you to represent both types of intervals effectively.
colorbar('ticks',[0.3:0.05:0.5])

Small size of colormap leads to discrete-looking colorbar.
surf(peaks)
cmap = jet(10);
colormap(cmap)
colorbar;
