barweb (BARgraph With Error Bars)

Plots a fully customizable grouped bar graph with error bars

Description

barweb.m calls the BAR and ERRORBAR MATLAB functions to produce bar graphs with error bars. The resultant graph is fully customizable, from group naming to legend inclusion to colormap setting. It assumes an m-by-n y-input matrix and plots m groups of n bars. The errorbar matrix must be setup the same way as the barvalues matrix (i.e. same dimensionality, matched values must have same indexes)

Syntax:
barweb(barvalues, errors, width, groupnames, bw_title, bw_xlabel, bw_ylabel, bw_colormap, gridstatus, bw_legend)

• Acknowledgements: This submission has inspired the following:; BarTwoYaxis, barwebpairs (pair bars within groups and between groups), Create Healthy Looking Error Bars
• MATLAB release: MATLAB 7.1.0 (R14SP3)

Pretty good, but it doesn't leave the user much control to make modifications. You should at least return the handles of the bar and errorbar objects, so that the user can modify their properties. Along the same line, you should also return the handle of the legend axes. I prefer leaving the legend (as well as title and labels) out for the user to do on their own, since it allows them to customize properties like position, fontsize, fontweight, etc.

Unfortunately for me, not compatible with Matlab 6.0.

Small problem with group labelling in R14.

Fix on line 124:
Add additional arguments to set(...)

set(gca, ..., 'XTick', 1:numgroups);

[Michael Frank]

Nice! produces very pretty graphs, generally very easy to use.

[Richard Cui]

Neat job!

[James Blake]

Works well with R2006a. Nice and easy to change the colours of the bars and such.

[Will Hunting]

Thanks a lot !

[Richard Lemon]

This works very well. What a big help. Thanks!

[germana ba]

thank you so much!

[Steve Fleming]

One of the very few oversights in the graphics toolbox is not having an easy way of plotting error bars! This is great and saved me a lot of time.

[Diana Bedolla]

For the plotting it works really good, but when I introduce the groupnames it repeats the same
first groupname in each x-tick. Any idea what could be the problem?? Thanks for the file!!

[J X]

This is very helpful, which helped me draw the graphs in a few secs.

[John Elve]

The script itself is good but it lacks the possibility of a variable number of input arguments!

[Dimka P]

Very helpful! Thanks!

[Andy C]

Just what I always wanted.

[Juan Hincapie]

Exactly what I needed!

[Kim Bostroem]

Coolomat!
Why hasn't the great Matlab thought of this himself? It's SO useful!

[H Hung]

great stuff.. any chance of updating it so that the errors can have an upper and lower bound like the matlab errorbar function?

[Amanda Whitmire]

Great - exactly what I needed. Thanks for sharing it.

[Y Guo]

Thanks! Good job! Matlab should consider incorporating this!

[alyssa smith]

you're my hero. this just saved me a mountain of trouble!!

[Ben Engel]

This was a great help - thanks!

[A VanderWyst]

 

[Jorge T]

Great! saved me a lot of time!

[Brajendra Singh]

Great!

[Lan Huong Vu Thi]

Thanks. It is useful for me !

[Nikolay Stoykov]

Great job, Bolu! Thanks.

[René Quilodran]

Thanks Bolu !!!!! you did a great job!!!

[Kshitiz Gupta]

Thanks. It is very useful.

[Mastaneh]

 

[Wenjia]

Excellent! That is just what I need.

[Félix Chénier]

Clean and simple, it does a very good job. Thank you

[Matthew]

 

[Greg Imamura]

Great program- I modified mine to allow for lower and upper errors

[Jaroslav Hlinka]

Thanks for the function! Useful, although I think I may have found an annoying bug: using 'error_sides = 1', when I save tiff file, it has the errorbar all the way down to x-axis (it is still ok when the initial figure is created). Using MATLAB R2007a on windowsXP. Any idea why/Any quick fix available?
PS. btw, the usage in the .m file might not be up to date - e.g. mentioning "barwebtype" parameter which is not amongst the function parameters.

[Dung Chu]

Great. I just need view(90, -90) after all to have horizontally-aligned bar charts.

[Luis Felipe Giraldo]

Nice!

[Anke]

really helpfull!

[Debanjan Goswami]

Really nice and easy. But I have got a problem. I can't plot the 'X-tick' like type1, type2... written in the example figure. I have the text for each bar in a separate cell array. How to incorporate?

Thanks

[Jesse Brown]

Handy function. One problem: when I save a figure with one-sided bars to .png or .tif, two-sides bars show up.

[Pearl]

 

[James]

Thanks Bolu! This is what I was looking for.

[Ross]

This is really nice. If using values in only one group (monthly rain data, for example), is there any way to add labels to the x-axis?

[Jeff Chen]

Works GREAT!

[C G]

Great. Thanks!

[Patrick A.]

 

[Erin]

to plot bars horizontal
view(90, -90)

or view(-90, 90)

[Juan Carlos]

Thanks!

[Ali Ali]

Thanks a lot

[Karen]

It would be nice if we could set different upper and lower error values... Otherwise quite cool

[Casey Ta]

 

[Casey Ta]

Thanks, this was very helpful!

[Rachel]

what are the options to set the gridstatus input to?

[Arturo Moncada Torres]

 

[Pearl]

Thank you!

[musi]

Pretty great:

it is working

 % groupnames
{'1000', '2000', '5000', '10000', '15000', '20000', '25730'},

[musi]

(The above statement is to put samples values associated with each bar in the x-axis)

[Arturo Moncada Torres]

Nice file. I recommend you to look at this post (http://blogs.mathworks.com/loren/2009/05/05/nice-way-to-set-function-defaults/) regarding variable inputs for functions.

Keep up the good work ;-)

good job

[David]

I seem to have run into a bug. I want to have a single bar for several groups and I set the groupnames variable to the names I want. But I end up with one group and multiple bars. I've tried inputing an mx1 vector and 1xm vector to see if that's the problem but both times I get the same results. Commenting out lines 120 and 121 fixed it. Any ideas?
