on the website my chart looks fine, i also need to export this one for pdf. unfortunately it doesn't look good... I don't understand why there are no spaces between the columns (but only in pdf!) how can I fix it? unfortunately I don't see any class, thanks to which I could add padding or something... also I don't know if I can write a script only for pdf? Thank you for your help!
