Mirror bar chart: 2 bar charts, 2 y axes, 1 x axis. Is it possible?

Hi all!

I want to get this mirror bar chart. Tried everything but nothing works.

Any idea?

For the lower figure do

 % if true
    % code
%  end
h= axes 
bar(...)
set(h,'Ydir','reverse');

This is exactly what I did in order to get the reverse bar.

Now, if you want to plot this reversed data set in the same plot of the other, sharing the x-axis, I got this plot:

Note that the 'normal' bar plot dissapeared.

a = (1:10)';
b = rand(10, 1);
c = rand(10, 1)*2;
figure
bar(a,b)
h1=axes
bar(a,b)
set(h1, 'Ydir', 'reverse')

Look, this is the script for each plot

a = (1:10)';
b = rand(10, 1);
c = rand(10, 1)*2;
figure(1)
bar(a,b)

figure(2)
h1=axes
bar(a,c)
set(h1, 'Ydir', 'reverse')

The plots:

How can I 'merge' the plot using the same x-axis?

Let´s be straight.

I want to get this bar plot

%if true
  % code
%  end
a = (1:10)';
b = rand(10, 1);
c = rand(10, 1)*0.75;
figure
h1 = axes
bar(a,b);set(h1,'Ydir','normal'); hold(h1,'on')
h2 = gca
bar(a,-c)
set(h2, 'Ydir', 'reverse')
axis([0 10 -1 1])

The y axis is negative. I need the y axis in positive integers.
