Very helpful.

Jefferson:

Unless I am mistaken, findobj will return a vector with handles to all objects that fit the bill. If you want to modify this such that you can use multiple different colors or alphas, refer to each separately. Something like:

figure
hist(data1,20)
hold on
hist(data2,20)
h = findobj(gca,’Type’,’patch’);
set(h(1),’FaceColor’,’r’,’EdgeColor’,’w’,’facealpha’,0.75)
set(h(2),’FaceColor’,’b’,’EdgeColor’,’w’,’facealpha’,0.75)
ylabel(‘counts’)
xlabel(‘gene-tree-length/species-tree-length’)
legend(‘no HGT’,’HGT’)
title(‘p = 0.5′);

Thanks, this is great.
Do you know how to draw a histogram with errorbars, the errorbars depending on the number of points in each bin of the histogram?
If you couuld help, that would be great

Exactly what I was looking for, but when I declare the second (and third etc) h and change facecolor it happens to all the histograms, not just the last one.
