It often happens - particularly with TX plots - that the horizontal axis labels are unreadable because they overlap each other. An attractive solution to this would be to allow the user to specify (somehow) an angle through which the labels should be rotated, such as the -angle <rotationDegrees> option used for canvas text items.

As an attempted workaround, I've tried to create a  TXPlot and then rotate all text items with the tag taxis, via $c itemconfigure $item -angle -270 but this makes the canvas slightly higher than it was and leaves it with a grey stripe at the bottom, while the rest of the canvas has a whit background.
