Here's a neat trick that might work for you.
1. Create a new chart (Straight table).
2. Add a calculated dimension and enter 1 (or something simple).
3. Add an expression with an empty string definition, but with the text you want as the label (therefore it CAN be calculated). Set Total Mode to No Totals.
4. Under Presentation, Hide the dimension column, and for the expression column select Vertical Columns Labels. You can control the positioning via alignment on the same tab. Unfortunately I don't think you can automatically wrap text so you would need to create extra expressions for each line.
Hope this helps
