Stacked bar plot with negative value

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.

Try this:

x = 1:12;
y1 = [data2' data3'];
bar(x,y1,'stacked')
hold on
bar(x, -data1, 'g')
hold off

It's working fine in classic workspace, but If I want to apply it in GUI graph, then it looks like this:

Used code:

x = 1:12; 
y = [data2' data3'];
bar(handles.axes1,x,y,'stacked')
hold on
bar(handles.axes1,x,-data1','g')
hold off

I would plot the figure first, since that works, then refer to the figure handle in the GUI call, rather than plotting them in the GUI call.

I do not routinely do GUI programming. I do not have enough experience with GUI programming to give you more help with the GUI part.

To create a figure handle, call the figure function before plotting to it:

x = 1:12;
y1 = [data2' data3'];

F1 = figure(1)                              % Define ‘figure’ & Create Handle
bar(x,y1,'stacked')
hold on
bar(x, -data1, 'g')
hold off

EDIT — Added figure call and figure handle.

I dont get it, how can I plot figure into GUI axes?

I don’t know what you are doing.

You will have to experiment.

Problem solved.

x = 1:12;
y1 = [data2' data3'];
bar(handles.axes1,x,y1,'stacked');
hold(handles.axes1);
bar(handles.axes1,x, -data1, 'g');
hold off;

Thank you!
