Make a 2D plot with one arbitrary axis

I’d like to make a 2D plot like the attached file in MATLAB. My problems are: 1. As the vertical axis is arbitrary, how can I plot a 1D- vector in MATLAB with x, y? I mean we have just data for x-axis (VEC) and how we can plot this vector in a 2D plot while the y-axis is arbitrary? VEC=[2 6 4.5 5 3 6.2 8 2.4]; 2. How can I add those dashed vertical line in a 2D plot? 3. How can fill the inside of the plot with colors? I mean left hand side of the dashed vertical line with a yellow (for example)? Is that possible to make different filling color for each section between the vertical dashed lines? (just like the attached file)
Best, Majid

You can start with something like this
bpoints = [6.88, 7.84];
color = summer(numel(bpoints) + 1); % or whatever colors you like
v = [5 6.2 8, 9];
h = plot(v, v, 'LineStyle', 'none');
h.Parent.Box = 'on';
ylim = h.Parent.YLim;
xlim = h.Parent.XLim;
h.Parent.YTickLabel = [];
bpoints(end + 1) = xlim(2);
offset = xlim(1);
for i = 1:numel(bpoints)
xx = [offset, bpoints(i), bpoints(i), offset];
yy = [ylim(1), ylim(1), ylim(2), ylim(2)];
patch(h.Parent, 'XData', xx, 'YData', yy, 'FaceColor', color(i, :), ...
'EdgeColor', 'none', 'FaceAlpha', 0.5)
offset = bpoints(i);
if i < numel(bpoints)
xline(h.Parent, bpoints(i), '--', 'LineWidth', 1.4)
h.Parent.FontSize = 12;
h.Parent.FontWeight = 'bold';
And then you can add text objects wherever you need (for dots/squares you can also use scatter or plot)

Not sure about it. What happens if you try without axes handle?
patch('XData', xx, 'YData', yy, 'FaceColor', color(i, :), ...
'EdgeColor', 'none', 'FaceAlpha', 0.5)
Or even only with xx and yy?
patch('XData', xx, 'YData', yy)

It does not work by each of the option. BTW there is no xline in MATLAB R2014B.
Thanks anyway, maybe I would change my MATLAB VERSION.

fill command will be suitable define your 3 squares as vectors , for y make it equal 1 for your graph I think
x1=[6.4 6.88 6.88 6.4 6.4];
y=[0 0 1 1 0];
x2=[6.88 7.84 7.84 6.88 6.88];
x3=[7.84 9 9 7.84 7.84];
d1=[6.88 6.88];
d2=[7.84 7.84];
hold on
