How to change bar graph style

I'm trying to create a bar graph, and set every bar a different style (lines, dots, circles and ext...).

In this example:

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
x = [10; 20; 50; 90];
bar(x,y);

All 3 bars have the same style.

How can I change it and set 3 differents styles for the 3 bars ?

I am adding some style changes to what @Luis given

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
x = [10; 20; 50; 90];
h = bar(x,y);
set(h(1),'FaceColor', 'w','LineWidth', 1, 'LineStyle',':');
set(h(2),'FaceColor', 'w','LineWidth', 1, 'LineStyle','--');
set(h(3),'FaceColor', 'w','LineWidth', 1, 'LineStyle','-.');

'FaceColor', 'w' -- Makes the color of bar white

'LineWidth', 1 -- Width of the border line of bar

'LineStyle',':' -- Dotted line

'LineStyle','--' -- Dashed line

'LineStyle','-.' -- Dash-dot line

enter image description here

For different style for each bar set

figure
hold on;
y = [2 2 3; 0 0 0; 0 0 0;0 0 0 ];
x = [10; 20; 50; 90];
z=bar(x,y);
ylim([0 15]);
set(z,'FaceColor', 'w','LineWidth', 1, 'LineStyle',':');
y = [0 0 0; 2 5 6; 0 0 0;0 0 0 ];
x = [10; 20; 50; 90];
z1=bar(x,y);
set(z1,'FaceColor', 'w','LineWidth', 1, 'LineStyle','-.');
y = [0 0 0;0 0 0; 2 8 9; 0 0 0];
x = [10; 20; 50; 90];
z2=bar(x,y);
set(z2,'FaceColor', 'w','LineWidth', 1, 'LineStyle','-');
y = [0 0 0;0 0 0; 0 0 0; 2 11 12];
x = [10; 20; 50; 90];
z4=bar(x,y);
set(z4,'FaceColor', 'w','LineWidth', 1, 'LineStyle','--');
hold off;

Use a handle output when calling bar

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
x = [10; 20; 50; 90];
h = bar(x,y);

That gives an array h of bar objects (of length 3 in your example), and you can set their aspect independently. For example,

set(h(1), 'EdgeColor', 'r');
set(h(2), 'EdgeColor', 'g');
set(h(3), 'EdgeColor', 'b');

gives the following graph in R2015b (the aspect will vary in other versions). enter image description here

Other properties you can change are 'BarWidth', 'LineStyle', etc. To see the list type get(h(1)).
