Currently, the length of labels affect my bars height. for example on the added image. Any idea if and how I can set a fixed height to the bar chart, no matter the length of my labels? I'm looking for a solution without slicing my label strings.

update: What is it with people that have no answer and decide to downgrade the question? If you have no answer or you know that there's no option for that, why not saying so? Where did humanity go...
