Use patch() with boxplot

Hi

I have a boxplot and want to color the chart area behind it.

How it that possible?

I am using patch und boxchart right now. But the boxplot overrides the patch, and if I use the patch after the boxplot its overlaying the boxplot.

I simply need a colorized area below a yline. maybe there is a different way to do so.

greetings

fill(rand(1,5)*3, rand(1,5)*sqrt(2), 'g');
hold on
boxplot(rand(5,3))
hold off

Note, by the way, that boxplot() does not fill areas -- it only creates line() objects.

Perhaps the OP doesn't have the stats toolbox, and therefore needs the boxchart function. The boxchart function converts the x-axis to categorical, so you need to massage the inputs a bit.

fill(rand(1,5)*3, rand(1,5)*sqrt(2), 'g');
hold on
ydata = rand(5,3);
xdata = ( 1:size(ydata,2) ).*ones(size(ydata)); % use implicit expansion
boxchart(xdata(:),ydata(:))
hold off

Thanks. You are right, I don't have that toolbox.

I also had to switch from categorical xaxis for the boxchart

xdata = ( 1:size(ydata,2) ).*ones(size(ydata)); % use implicit expansion

helped a lot
