Fix long labels visibility for QBarChart...
Fix long labels visibility for QBarChart Long labels are truncated vertically and horizontally so that they fit into the space available. There's no need to hide the labels explicitly as they are already truncated to the space available. The truncatedText() method now takes into account also the height of the space available.
