axis.x.tick.multiline cutting too much of label

Hi!

My labels were cut off before I found the new version with multiline possibility.
For space reasons I can only show one line, so I simply added
`multiline: true,`
`multilineMax: 1`
to the axis.x.tick.
Now, either the whole label is shown or nothing. Couldn't it just calculate what's possible to show and then add the dots "..."?

Thanks for your help
