Hi Hamish,
I think that I didn't make myself clear. I meant the white space
between the histogram bars and the graph axes - the most left bar
touches the border. For comparison between what I find good and bad
see:
- bad: http://www.cs.put.poznan.pl/wjaskowski/tmp/histogram.pdf,
- good: http://www.cs.put.poznan.pl/wjaskowski/tmp/histogram2.pdf
