I want to create a figure that looks alike the attached, where I have a bar and when the value is 1, it is filled in blue, and when the value is 0 it has no colour.
The x axis must be datetime values and the bars must have filled colour, i.e. they cannot be outlines
Is this possible to do on MATLAB?

The bar function creates a barchart. What I need is a sideways bar with some parts filled in and other parts not, alike the figure. Unless I am mistaking your direction?

Look at barh() function and see if you can figure it out.

It would help to have an example of your data.
That aside, the sort of plot you want to do is straightforward.
Try this:
v = sort(rand(1,20)); % Create Vecttor Of Independent Variable Values
figure
yv = [0 0 1 1];
hold on
for k = 1:2:numel(v)-1
patch([v(k:k+1) fliplr(v(k:k+1))], yv, 'b')
end
hold off
It would likely be relatively straightforward to adapt this to a datetime vector.
