making a histogram goes wrong

hello,

I have made a histogram with certain data. The histogram matches what I need to find, except for those little bars, with the black border around, at the bottom are error. I would like to get rid of them, but I do how and I don't know why they are there

h1=histogram(HartslagInRust(geslacht=='man'),'Normalization','probability')

hold on

h2=histogram(HartslagInRust(geslacht=='vrouw'),'Normalization','probability')
