Creates nice boxplots from data. You don't need a toolbox. Simple yet fully featured.

File Information
Description

bplot(X)
This function will create a nice boxplot from a set of data. You don't
need a toolbox.

    bplot(D) will create a boxplot of data D, no fuss.

T = bplot(D) If X is a matrix, there is one box per column; if X is a
              vector, there is just one box. On each box, the central
              mark is the median, the edges of the box are the 25th and
              75th percentiles
              array 'T' for a legend. You can add the legend as legend(T)

T = bplot(D,x) will plot the boxplot of data D above the 'x' value x

T = bplot(D,y,'horiz') will plot a horizontal boxplot at the 'y' value of y

T = bplot(...,'Property', . . . )
T = bplot(...,'PropertyName',PropertyValue, . . . )

% Jitter feature
The boxplot has a cool jitter feature which will help you view each
outlier separately even if two have identical values. It jitters the
points around the other axis so that you can see exactly how many are
there.

% Examples:
bplot(randn(30,3),'outliers')
bplot(randn(30,3),'color','black');
----
X = round(randn(30,4)*5)/5; % random, with some duplicates
T = bplot(X,'points');
legend(T,'location','eastoutside');

% This function was created for inclusion in my larger nhist function.

I found the same error than Brian and DKM I found a way to solve it by changing lines 304-313 to

for ii=1:length(hReg)
set(hReg(ii),'HandleVisibility','off')
end

% % remove all remenants of legends
if forceNoLegend
for ii=1:length(hReg2)
set(hReg2(ii),'HandleVisibility','off')
end
end

Thank you very much for submitting this code. Works well, easy to customize and save me ton of time :D

I've got the same issue as Brian, "no Annotation property on the Rectangle class" error. Worked fine until I upgraded to 2015a. I wonder what changed?

Nice contribution, thank you. Really like that I can overplot box plots on top of other plots, Matlab's boxplot() will not do this.

When I try to plot a matrix D, larger than a vector, in MATLAB R2015a, I get the following error: (I don't get the error in R2014b)

"Error using get
There is no Annotation property on the Rectangle class.

Error in bplot (line 311)
set(get(get(hReg2(ii),'Annotation'),'LegendInformation'),'IconDisplayStyle','off'); % Exclude line from legend

Error in bplot (line 99)
bplot(x(:,ii),ii,'nolegend');"

When plotting a vector such as: "bplot(z(:,1));" It plots fine, but as soon as we go to a higher dimension (such as: "bplot(z(:,1:2));") I receive the above error.

It's very useful. Is there any way to display values on every plot please?

Easy to produce plots that communicate results well

Exactly what I've been looking for. Love the simplicity of the features!

It's quite useful. Wish there was a way to perform the analysis when the number of observations for each experiment are not the same.
