Fix label truncate issues with multiple axes...
Fix label truncate issues with multiple axes If there were multiple axes on single side of the chart, the axes wider/higher than average never got their preferred size, causing labels to truncate. Fixed by calculating the required squeeze ratio instead of just blindly using even fraction of available space. Task-number: QTRD-1897 Reviewed-by: Mika Salmela
