Hello! I want to make a plot like this, but I don't know exactly how.
More specifically,I want to plot the possible values of flux variability for some reactions.
Could someone guide me? Thank you.

Easier than you think.
First, write a little function that will plot a bar of fixed height, between two points on the x axis. It might look like the function called xbar below.
Next, call that function repeatedly, once for each horizontal bar.
Finally, change the y axis to have a different set of tick labels. It looks like you will need to set the YTickLabel property on the axes. For example:
H = get(gca);
Now you can reset those tick mark lables as desired. And they need not be numbers.
% On the current figure, creates a horizontal bar
% of unit height, between y and y+1, and between xlo and xhi
% this can be as simple as one call to fill.
barpolyx = [xlo,xhi,xhi,xlo];
barpolyy = [y,y,y+1,y+1];
Should be pretty simple. Spend some time learning to use the basic tools.
