Custom text in bar chart reports


I have a report containing a Bar Chart and I want to display each bar label vertically. I set the Label position to “Up 90”. When I have a long string assigned to a specific label, it gets truncated. I would like to be able to show all the string. Is it possible to split the text in two lines or is it possible to adjust the plot’s height dynamically? I suppose I have to implement configureChart() but I really need help on that.
