Bar with errorbars

This code plots bars with errorbars, as simple as that.

Description

As of now (2009-Jul-13), MATLAB doesn't have a built-in function to plot bars with with error bars on top of them. This function solves that problem.

To a beginning user, this provides a very simple way of plotting bar with errorbars with a simple command:
errorbarbar(y,e); % where y is the height of the bars and e is the limit to plot as error bars (of length 2*e, about y).

For an intermediate user, this function provides the handles to the BAR and ERRORBAR lines for further modification.
[b,e] = errorbarbar(y,e); % or ...
[b,e] = errorbarbar(x,y,e); % where x is center location of the group of bars

For an advanced user, this function also provides ways to modify any and all of the bar and line series properties while plotting it in the first place.

Example:
barSettings = {'facealpha',0.5,'edgecolor',[0.5 0.5 0.5]};
lineSettings = {'linestyle','--','linewidth',2};
[b,e] = errorbarbar(x,y,e,barSettings,lineSettings);
set(b,'facecolor',[0 0.5 0]); % set all bars to color green

Hint: You can use the lineSettings variable to use distinct upper and lower limits.

What it DOESN'T do:
1. Plot horizontal bar graphs
2. Work with bar(y,e,barSettings,lineSettings). Instead, use:
      bar(x,y,e,barSettings,lineSettings).

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: Because of the way this function is written, it should be backwards/upwards compatible, as long as BAR and ERRORBAR functions are consistent with R2007b.

It is not as simple as you said. Would you mind putting up an illustrative example (especially for stacked bar plot). I would really appreciated it.

Thanks,

@Shatrughan: errorbarbar(1:5, rand(5,2)*10, rand(5,2),{'stacked'});

Thanks a lot !!

"Hint: You can use the lineSettings variable to use distinct upper and lower limits."
Can you give me an example? I need to draw asymmetric error bounds. Thanks.

[Venn Ravichandran]

x = 1:10; % x-axis
y = rand(10,2); % bar-heights
L = rand(10,2)*0.01; % Lower limit
U = rand(10,2)*0.03; % Upper limit
barSettings = {};
lineSettings = {U, 'linestyle', 'none'};
errorbarbar(x, y, L, barSettings, lineSettings);

Other error bars I find cannot deal with asymmetric error bounds. This one works like a charm.
