MATLAB: Stacked bar plot with negative value

Question

Hello, I need to make stacked bar plot with my data to look like this:

My data set:

data1 = [0 0 3.16 25.08 46.87 57.97 39.25 28.81 10.63 0.06 0 0]
data2 = [74.00 152.68 319.99 514.05 635.73 647.61 645.32 569.51 398.48 226.13 84.88 52.08]
data3 = [628.07 497.66 426.97 285.56 220.67 184.04 212.71 239.93 318.25 451.61 545.02 626.39]

If I make it like this:

x = 1:12;
y = [data2' data1' data3'];
bar(x,y,'stacked')

It looks like this:

So I need to green part be like negative values.

y = [data2' -data1' data3'];

and graph then look like this:

How to get green part to negative side of y axe?

Thank you for advice.
