How to change boxplot filling with newer Matlab versions?

Hello,

I would like to change the filling of the boxplots

boxplot(y,'Labels',{'1','2','3'},'Color','k')
xlabel('X')
ylabel('Y')
title('XY')

Now I would like to fill each boxplot with a color like black, gray and dark grey.

So:

First Boxplot => black

Second BP=> gray

Third BP=> dark gray

Unfortunately the 'children' code won't work anymore.

Can you help me?

Thanks.

Just use the 'Colors' named option with an rgb array...

I did it like this:

h = findobj(gca,'tag','Box');

This selects only the box color :)

The implementation leaves much to be desired...I had presumed the colors with the 'filled' option would work as one would expect -- who woulda' thunk they'd have broken it such that if use that, then can only get the narrow little boxes; the 'traditional' style and 'width' parameters are ignored.

Worth a bug/quality of implementation report.

Why it doesn't return a handle to the object also breaks any symmetry with other plotting routines -- TMW continues with the trend to less and less coherence in user interface design and implementation...making things act so differently from one to another so lessons learned aren't... :(

You can specify an array for the color, it should have the same size as the columns in y.

boxplot (y, 'Colors', ['k' 'r' 'b'], 'BoxStyle', 'filled');

or for your colors in rgb triplets:

boxplot (y,  'Colors', [0,0,0; 0.5 0.5 0.5; 0.3 0.3 0.3], 'BoxStyle', 'filled');
