Bar graph issue

[Vlado Kršlin]

Hello. bar graph code with four diferent bars is attached here which by the way works, but I don't like the way it is shown. Bars covers each other, instead of this I would like to have one by one bar close together (four of them for each day). X axis represent days in month.

In case you need more informations just let me know about.

Thanks in advance, Vlado
