[metapost] Statsmac histogram

[David Arnold]

Hi,

I have:

data(mine)
10,10,
20,20,20,20,20,20,
30,30,30,30,30,30,30,30,30,
40,40,40;

beginfig(1);

	interim frequencymode:=1;
	usedata(mine,x);
	setrange(0,50,10cm,0,10,3cm);
	bounds 5,15,25,35,45;
	histogram x;
	autograd;

endfig;

end.

I am using Anthony Phan's statsmac package:

http://www-math.univ-poitiers.fr/~phan/statsmac.html

mps.tar.gz

I am trying to figure a way so that the height of each bar in the histogram equals the count. So, I'd like to have the first bar have height 2, the second have height 6, the third have height 9, and the fourth have height 3.

Can anyone help?

David.
