How to plot just a colorbar without plot?

I would like to plot just a colorbar on a subplot without real figure. I can do this, but I want to shrink the figure area. How to make zero figure width and wide colorbar?

A colorbar must be attached to an axes, so you have (at least) two options:
- Create an axes, attach a colorbar, then make the axes invisible.
- Create an axes, attach a colorbar, then move the axes and colorbar separately.
For example:
ax = axes;
c = colorbar(ax);
ax.Visible = 'off';

The Visible property on axes controls the visibility of the axes (the backdrop, the rulers, the ticks, etc.) but does not control the visibility of the plots within the axes (lines, bar graphics, etc.). Is this the issue you are seeing? If not, please post some example code along with a screenshot of what you are seeing, and someone should be able to help you.

One can also center the colorbar in the figure as follows:
hf = figure('Units','normalized');
colormap turbo
hCB = colorbar('north');
set(gca,'Visible',false)
hCB.Position = [0.15 0.3 0.74 0.4];
hf.Position(4) = 0.1000;
