Could add an item to an axis. This is a fundamental feature.
You can make a customizable(re-allocatable) view for each item. Moreover, you can place a spacer or a label between values.
For example,
- About item A, you may want to show values of
{ W, X, Y, Z }as the order of{ W, X || Z, Y } - About item B, you may want to show values of
{ W, X, Y, Z }as the order of{ W || X, Y, Z }
You can allocate value for an item more than one place like { W, X, Z || W, Y, Z }
