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:
plot(rand(1,5))
H = get(gca);
H.YTickLabel
ans = 9×1 cell array
{'0' } {'0.1'} {'0.2'} {'0.3'} {'0.4'} {'0.5'} {'0.6'} {'0.7'} {'0.8'}
Now you can reset those tick mark lables as desired. And they need not be numbers.
function xbar(y,xlo,xhi,barcolor)
% 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];
fill(barpolyx,barpolyy,barcolor)
end
Should be pretty simple. Spend some time learning to use the basic tools.

Wait. You were the one who implied you knew that.
I have no idea what it means to have ALL of the values shown. But surely you might be able to choose two percentiles of your data. Perhaps the 5 and 95% points from the data, thus excluding a few outliers. Or the 1% and 99% points. Or just the max and the min. Your choice.

This looks to me like a horizontally oriented box plot. You can easily create such plots using boxchart or boxplot. Since you want a legend, I recommend using boxchart.

The function from the Stats toolbox is named boxplot (not boxchart).

Yes, there is boxplot! Thank you!
